thanks for having me! important note idk if it was editing or I misspoke in blood rushing excitement--probably the latter bc I mean, it's wired magazine--the diastolic / lower number is still an arterial pressure read veins are passive / not part of BP but still all a closed circuit and this is why i'm not a cardiologist.. at the dismay of uncles and aunties everywhere i'm sure 😮💨
No. Health care workers are taught to present info at a 5th grade reading level. All patient education materials in medical setting also at 5th grade level.
He is just like this in person. He was my hematologist a few years ago. He treats all his patients with respect and kindness, and most of all, he listens to you. Dr. Juneja is just a wonderful human.🙂
@@emmy9732 For example, he said that the diastolic blood pressure, the second value, refelcts the pressure in the veins. This is untrue, it reflects the lower boundary of the variation of arterial pressure.
Actually a lot of baseline “normal” things in medicine are based on adult white males which of course being the diverse world that we are, isn’t actually the real normal. Thanks doctor for reminding us of that.
I noticed that ethnic doctors ( like him ) always do so. White doctors NEVER care abt these differences. If you see skincare studies that test black and asian skin theyre never done by white doctors. All the beauty skincare products are made for White skin
I hope most doctors are aware of that - imagine getting a blood test and they think it's all normal because of these specific averages made centuries ago 🥴

Hats off to hematologists frfr. My daughter’s hematologist had the tiniest hunch that my daughter had AML due to consistent blood testing and other health factors that put her at extremely high risk. She was scheduled for a bone marrow biopsy that same week. By Monday of the next week, her hematologist gently delivered the diagnosis, thoroughly explained her treatment plan, and had us admitted to hospital the next day. She would make sure to speak to us when she was in for morning rounds and really held our hand through it. My daughter is now in remission thanks to her. I’m so grateful for all the very nerdy people who study blood lol ❤

In that case, I also try to simplify what I'm talking about without being condescending--they may not understand my job, but I probably don't know theirs either.
the way he answered the question related to period blood makes me so happy.. like for once there is no reference to 'the amount of blood being lost is minimal so just relax, don't exaggerate' etc :)
@@rosmarbal gotta quote @canesugar911 on here - What amount is 36%? 50ml?, 100ml?,500 or 2ml? Or 1000?

You say that "you are not losing anywhere near the amount of blood you think you are losing as the vast majority isn't blood",.....so i ask again, what is the exact amount of blood being lost for all the women? while they say it's somewhere around 40 - 90ml, it is more than that for a lot of women.. so there is no exaggeration there
@@rosmarbal It would not have been correct. Iron deficiency is very common among people who menstruate regularily and is underdiagnosed and undertreated. It is so common in fact that the reference values for hemoglobin in women are lower than those of men because such a large proportion of the "healthy" population is anemic.
Thank you for talking about standard ranges for blood tests and different geographical areas w/blood types. I was a grown grown adult before a hematologist was able to help me understand my ridiculous life long anemia & alpha thalassemia.

As someone who underwent a stem cell transplant earlier this year to hopefully keep my mutliple myeloma in remission, and who had to have sooooooo many platelet transfusions while I was in the hospital for a month (and for several weeks after) to keep me alive, I'm eternally grateful to those who donate blood and platelets!!
My mom was sick for months despite my pleas, 1 night she couldn't take it. They found a *BLOOD CLOT* in her lung. She would have died if she waited longer.

It takes a long time to bleed out to the point of being in danger when on your period, trust me. Several years ago, I had a really heavy flow that lasted several weeks (I'm talking about half a box of pads per day type of heavy flow). I went to urgent care, was told to keep an eye on it, but later that week I passed out in the shower, only to wake up to a doctor explaining to me that I was borderline comatose because my H&H got so low. It was so bad that they kept me in the ICU for 6 days and I ended up needing a total of 9 units of blood... almost an entire person's worth. I can honestly say without donated blood, I'd be dead right now. SO PLEASE DONATE BLOOD IF YOU'RE ABLE!
And if you’re using half a box of pad’s every day for a week, you should DEFINITELY go see a doctor. Actually, considering that’s the amount you used and you needed a whole persons worth of blood to be ok again… an eighth of a box is probably where people should start checking lol.
I was going through super plus tampons every 2-3 hours. The best treatment is birth control but birth control has caused me twice to end up with pulmonary embolism’s in my lungs arteries (huge clots obstructing almost all blood flow). I have naturally higher clotting factors that saved my life in a car accident where I was ejected 40 ft and should have died, but apparently it’s also causing heavy clots during my period too. So it’s a lose lose situation. But I saw a hematologist in the ICU after my lung clots and they made minimal effort to help or do anything. The pulmonologist was the one explaining what she should have.
@@marquisdelafayette1929ditch the birth control and get on calcium d glucarate. I had the same issue as you with the extremely heavy periods, I had to change my super tampon HOURLY. After a couple months of consistently taking CDG, I only use 4-5 tampons a day and zero clots.

"You gave them the wanted poster" is such a wonderfully concise way of explaining vaccinations. As with the mosquito bite thing... I've always wondered, as someone who appears not to get stung, if it's indeed a lack of stinging or a lack of reaction to the sting. I've felt a mosquito sting plenty of times, but it did not lead to an itchy spot in several instances. It may be an added layer to this question.
This was great! As always Wired knocked it out of the park. Now, as a phlebotomist, I’m hoping they’ll consider doing a Phlebotomy Support video to help answer some questions and lessen some of the stigma around having your blood drawn and just why it’s so important! We aren’t heartless monsters with needles here to make your life difficult, we’re a super important component of the healthcare chain. But to have a video all about blood really made me smile!
Basically, it’s like going to the grocery store and picking out which candy will give you the best sugar high. So, if you think about it, mosquitos are addicts. Go figure. 🤣
If biology was explain like this in middle/high school, I wouldn’t have fallen asleep. Most of the things I was supposed to learn in middle/high school I ended up teaching myself in college
For the amount of blood in a peroid question the biggest thing is that only about 36% of it is actually blood. 2 thirds of it is other stuff like the uterine wall and other tissues and secreations. So your not losing anywhere near the amount of blood you think you are as the vast majority isnt blood.
What amount is 36%? 50ml?, 100ml?,500 or 2ml? Or 1000? The percentage of blood in the menses composition does not reflect the actual amount of blood being Channelled out of circulation. The menstruating population would not have issues like anaemia or certain blood deficiencies if they weren't losing a significant amount of blood. You say that "you are not losing anywhere near the amount of blood you think you are losing as the vast majority isn't blood",.....so i ask again, what is the exact amount of blood being lost for all the women?
@canesugar911 maybe it's less losing too much blood, and maybe more someone's body not being able to do its job to replace the amount that comes out during menstruation?
Not to mention that the uterine lining forms over the entire time of the cycle. So the amount lost over a week has been around for 3 weeks and your body was making more the whole time.
1:46 This is not accurate. The bottom number of conventional blood pressure notation is diastolic blood pressure, which means the lowest pressure within the major arteries. It is not the same as the pressure inside veins.
You learn something new everyday. Great video, thank you Dr. Sanjay. There was just one teeny tiny error, at 7:57 I think he meant to say baby blood cell instead of baby blood vessel because a reticulocyte is actually a immature red blood cell. 😊
The only caveat to what he said is that the diastolic blood pressure (the number on the bottom of the blood pressure measurement, i.e. the 80 of the 120/80) is NOT a measurement of the pressure of the blood in the veins returning to the heart. Instead, it represents the measurement of the lowest pressure present in the arteries, that continues to move blood forward, even when the heart is relaxing.
Shame on Wired for making the thumbnail question not only the VERY LAST one but one of the most unsatisfactory answers. I waited through that whole video for nothing.
I am always so happy to see one of these episodes pop up. Blood has always intrigued me, especially since being told I was apparently "allergic" to it. 😂
This was one of the most interesting and informative TechSupport videos. I know next to nothing about biology, and am keen to watch more of this type of content.
Why are they asking questions about blood pressure to a hemathologist? He got almost everything he talked about that wrong. Those are best left for a cardiologist. Venous pressure isn't equal to diastolic BP, it's much much lower. Diastolic BP also isn't what happens after the blood finishes giving oxigen and has nothing to do with oxigen in fact. Not all kinds of fainting are like that, and not all kinds of fainting are benign like the blood drawing one.
Also re: mosquitos bites - Some people may be getting bit just as much, but with no reaction. I used to get itchy mosquito bites. Then some time as a young adult I noticed that I didn't get the itchy bumps anymore. I've even watched mosquitos bite me to make sure I wasn't just slapping them before they had a chance to do their thing. I offer my blood up to science if anyone would like to develop a mosquito vaccine 😆.
Good information but I do have to (respectfully) correct one thing Dr. Juneja said. He stated that venous pressure is the bottom number on a blood pressure measurement. The bottom number is the lowest pressure in the arteries during the cardiac cycle. Pressure in the veins is usually 8-10 mmHg.
Came here for this and was hoping for exactly this type of comment. Less of an „uhm, actually“ but just respectful help. Must admit, I had to rethink everything I know about my knowledge about blood pressure there for a second xD
I think it was trying to make it easier for a layperson to understand. RN-Me knows the definition but has had to explain it many times in less technical language.
"Oxygen is the fuel on every cell in your body" The Engineer in me died a little inside with this statement. Also, as important as carrying oxygen in is carrying CO2 out. Also centrifugal/centripetal: Just stop it, you never get it right. Centrifugal force is REAL in a rotating reference frame. It doesn't get any more rotational than a centrifuge. Expressing things in the "real" centripetal force is much more confusing.
Theres actually laboratory scientist who specialize in haemtology, coagulation and transfusion that do lab testing to detect haemtolgicial disorders and then doctors in haematology that treat the haematological diseases
So, I live in Scottsdale, Arizona, and I didn't realize we had mosquitoes here for years. Then, when walking my dog with a neighbor, I realized we do have mosquitoes as she repeatedly got bitten. However, if I travel to Colorado, I'm apparently fair game there for mosquitoes. Honestly, I would love to know the science behind why Arizona mosquitoes avoid me like poison, but Colorado mosquitoes love my blood as much as the next person.
I have anemia(I've been anemic for a long time), a high platelet count, and small pink blood cells. I take ferrous sulfate for it, my platelet count is going down gradually. I need a CBC and panel before I can know if there have been any other changes.
Weirdly enough, plasma can and does change colors. When I used to donate plasma some years ago, the plasma was a pretty peachy mango color. I took no prescription medication and that was the natural color of my plasma. But the blood bank workers explained that women who take birth control pills or hormone replacement therapy often have olive green/ pea green plasma due to the medication in their body.
The first question! My daughters are B+ and I'm O+. When they were born, my blood attacked theirs and caused them to have very low hemoglobin and high bilirubin. They told me it's likely that when I had my youngest son (also B+), my body created antibodies so when I got pregnant with my twins it was prepared to attack. I never knew that this was even a thing that could happen. Thankfully they are doing well and I'm fixed so no more kids over here lol
I have a low white blood cell count. I really appreciate you bringing this up because every time I go to the doctor for a physical, they are so worried about my low WBC count. But every time I get it checked at a Hemotologist (child and adult) the numbers are consistent. They keep wanting to do tests and I am like... or this is just my normal level?
That was so informative, great lecturer! As for mosquitoes, i know that ones in Alaska would bite anyone around me, but I wasn't touched even once. But mosquitos in other countries and places didn't discriminate.
Great video. Loved how all the experts called here are so great with explaining and communicating! It would be amazing if Wired can collaborate with Dr. Mike. I follow his channel and as a primary care physician, he uploads such great videos about medicine and myths and overall healthcare. Would love to see him answering Twitter questions here 😁
What always blows my mind about the blood types... humans have been around for such a longish time that I'm surprised all the time that more people aren't AB+ by now... facinates me. Which another thing that interests me... my entire family... both on my mothers side and my fathers side are all A+... yet my daughter... O+. Confusing. Some where in my parents history... there is a recessive O that I apparently inherited... completely baffled my mind. Liking your show... as a Lab Tech... this is awesome. Thanks.
i remember hearing a long time ago that it had something to do with the iron in your blood. it's still not actually figured out though? if it hasn't, this would be an interesting coincidence, but i rarely get the opportunity to eat red meat anymore so i suspect my iron levels are quite low. i haven't had issues with mosquitoes in over a decade. but i used to have a ton of issues and i know my dad still has issues etc. so i always took that info about needing iron to be fact.
When I was a teenager, I went to an oncology camp for a week out in the woods every summer until I turned 18. One year (my second, I think), I was receiving chemotherapy treatments that continued during my stay. Interestingly, through the entire week I was there, I only got bit by a single mosquito. However, other years, I ended up getting more than one bite so I would assume that mosquitos can smell the toxic chemicals running through my blood. Just something I found intriguing.
Dr. Juneja is a really energetic guy with great information delivery. Wired has been doing great finding these charismatic science professionals on the program.
Really happy to hear about the white blood cell counts. I have a healthy but high count (the platelet donation ppl love me) After the first time I gave they told me to ask my doctor- nothing wrong, just an unusually high count especially for the area. I am not white. That probably explains it.
As for the last question, the one on mosquitos, I doubt blood type plays a part in whether or not you will be eaten alive by mosquitos or not. My mum and I are both A+. If they ever bite her, she gets a teeny tiny mark on her skin. If I do, most times I get a bump that can be the size of a cherry tomato and can leave a mark on my skin for up to 2 months. I read that there’s some syndrome and it’s got to do with you being allergic to mosquito saliva.
This was really interesting and the Dr. Juneja is gorgeous, so that didn't hurt. I'm one of those people who mosquitos hate. I've stood by with mosquitos on me with no bites while everyone around me get eaten up like a buffet supper.
thanks for having me! important note idk if it was editing or I misspoke in blood rushing excitement--probably the latter bc I mean, it's wired magazine--the diastolic / lower number is still an arterial pressure read veins are passive / not part of BP but still all a closed circuit and this is why i'm not a cardiologist.. at the dismay of uncles and aunties everywhere i'm sure 😮💨

This dude's a great teacher, bring him on more!
"You gave them the wanted poster" is such a wonderfully concise way of explaining vaccinations.
As with the mosquito bite thing... I've always wondered, as someone who appears not to get stung, if it's indeed a lack of stinging or a lack of reaction to the sting. I've felt a mosquito sting plenty of times, but it did not lead to an itchy spot in several instances. It may be an added layer to this question.
Well for the first time, "wtf" isn't censored...
Cry about it
It was too much to hear the f word like that for me. But I appreciate all the infob
I think they forgot to censor it
This was great! As always Wired knocked it out of the park. Now, as a phlebotomist, I’m hoping they’ll consider doing a Phlebotomy Support video to help answer some questions and lessen some of the stigma around having your blood drawn and just why it’s so important! We aren’t heartless monsters with needles here to make your life difficult, we’re a super important component of the healthcare chain. But to have a video all about blood really made me smile!
soooo.... Why does some people get mosquitoes bites more than others?
High CO2 in the blood. High bicarbonate.
They don’t bite me and puzzling to people around me.
O blood least affected not as sweet
Basically, it’s like going to the grocery store and picking out which candy will give you the best sugar high. So, if you think about it, mosquitos are addicts. Go figure. 🤣
@@suelindsey1372 not as sweet 🥲
If biology was explain like this in middle/high school, I wouldn’t have fallen asleep. Most of the things I was supposed to learn in middle/high school I ended up teaching myself in college
For the amount of blood in a peroid question the biggest thing is that only about 36% of it is actually blood. 2 thirds of it is other stuff like the uterine wall and other tissues and secreations. So your not losing anywhere near the amount of blood you think you are as the vast majority isnt blood.
What amount is 36%? 50ml?, 100ml?,500 or 2ml? Or 1000? The percentage of blood in the menses composition does not reflect the actual amount of blood being Channelled out of circulation.
The menstruating population would not have issues like anaemia or certain blood deficiencies if they weren't losing a significant amount of blood.
You say that "you are not losing anywhere near the amount of blood you think you are losing as the vast majority isn't blood",.....so i ask again, what is the exact amount of blood being lost for all the women?
@@canesugar911Yeah. There's blood in the uterine wall bits that slough off, as well as where the remaining tissue will heal.
@canesugar911 maybe it's less losing too much blood, and maybe more someone's body not being able to do its job to replace the amount that comes out during menstruation?
Not to mention that the uterine lining forms over the entire time of the cycle. So the amount lost over a week has been around for 3 weeks and your body was making more the whole time.
@@m.g.5073 read my comment again
where do you keep finding these hot experts
Wow. This doc is extremely intelligent, you can tell in the way he speaks and carries himself. It was a joy listening to your explanations doc!
1:46 This is not accurate. The bottom number of conventional blood pressure notation is diastolic blood pressure, which means the lowest pressure within the major arteries. It is not the same as the pressure inside veins.
You learn something new everyday. Great video, thank you Dr. Sanjay. There was just one teeny tiny error, at 7:57 I think he meant to say baby blood cell instead of baby blood vessel because a reticulocyte is actually a immature red blood cell. 😊
There are several obvious errors in his explanations. This maey me wary of all the other videos in this series.
He’s a really good teacher, makes complicated topics very easy to understand
I like how he talks with his hands. I know a bunch of people like that
I'm like that too. I tell folks that if you tie my hands, I can't talk. I need at least one otherwise I'm silent.
🤌🤌🤌🤌🤌🤌
Very Indian stuff to do. 😂
He explains these concepts so well. Definitely one of the best experts featured on this series so far!
The only caveat to what he said is that the diastolic blood pressure (the number on the bottom of the blood pressure measurement, i.e. the 80 of the 120/80) is NOT a measurement of the pressure of the blood in the veins returning to the heart. Instead, it represents the measurement of the lowest pressure present in the arteries, that continues to move blood forward, even when the heart is relaxing.
Shame on Wired for making the thumbnail question not only the VERY LAST one but one of the most unsatisfactory answers. I waited through that whole video for nothing.
This should start teaching.
He can easily make student understand difficult topic so easily.
I am always so happy to see one of these episodes pop up. Blood has always intrigued me, especially since being told I was apparently "allergic" to it. 😂
This was one of the most interesting and informative TechSupport videos. I know next to nothing about biology, and am keen to watch more of this type of content.
I learned a lot. Thanks wired for this series.
"..Yo yo come, we need to regenerate this.." 😂
This man is amazing
My mom is definitely one of those people that mosquitoes favor! She will get twice as many bites as anyone else in the vicinity, always. Poor mom!
*chefs kiss* fun, engaging, and informative. Makes me want to learn.
Why are they asking questions about blood pressure to a hemathologist? He got almost everything he talked about that wrong. Those are best left for a cardiologist.
Venous pressure isn't equal to diastolic BP, it's much much lower. Diastolic BP also isn't what happens after the blood finishes giving oxigen and has nothing to do with oxigen in fact. Not all kinds of fainting are like that, and not all kinds of fainting are benign like the blood drawing one.
thank you! I'm surprised no one else picked up on that
I know right! I was like, WTF?
I caught that too… like venous pressure is 2-10 mmhg not equivalent to your diastolic BP.
I wish this guy had been Noah, because he (and his explanations) slap.
He’d make a great science teacher. Kids will love him 😂
Also re: mosquitos bites - Some people may be getting bit just as much, but with no reaction. I used to get itchy mosquito bites. Then some time as a young adult I noticed that I didn't get the itchy bumps anymore. I've even watched mosquitos bite me to make sure I wasn't just slapping them before they had a chance to do their thing. I offer my blood up to science if anyone would like to develop a mosquito vaccine 😆.
Good information but I do have to (respectfully) correct one thing Dr. Juneja said. He stated that venous pressure is the bottom number on a blood pressure measurement. The bottom number is the lowest pressure in the arteries during the cardiac cycle. Pressure in the veins is usually 8-10 mmHg.
Who cares
Came here for this and was hoping for exactly this type of comment. Less of an „uhm, actually“ but just respectful help. Must admit, I had to rethink everything I know about my knowledge about blood pressure there for a second xD
@@adityagurung017For science? Truth? Having correction information?? Think better.
Almost sure it's an oopsie more than a lack of knowledge. Or maybe he holds the hand device upside down 😂
I think it was trying to make it easier for a layperson to understand. RN-Me knows the definition but has had to explain it many times in less technical language.
I really liked when you personalized the platelets saying “yo, yo… come! We need to regenerate” 😊
I was wondering when the next tech support video would come, after the last few weeks. I’m glad it’s back
My hematologist saved my life. He works so hard to keep me alive. Regardless of what my insurance company approves. I'm still here because of him.
Yes , it’s nice to have an advocate for your complex health ❤
Sadly I'm the one in my group that will always get bitten. I can have 5-10 mosquito bites compared to their one bite. Hate it.
"Oxygen is the fuel on every cell in your body"
The Engineer in me died a little inside with this statement.
Also, as important as carrying oxygen in is carrying CO2 out.
Also centrifugal/centripetal: Just stop it, you never get it right. Centrifugal force is REAL in a rotating reference frame. It doesn't get any more rotational than a centrifuge. Expressing things in the "real" centripetal force is much more confusing.
The explanation of the blood pressure is completely wrong. The high and low numbers are systolic and diastolic arterial pressure.
Did not anticipate that crocheted platelet. So cute!
My friend and her mother made that plushie! Sanjay is/was her doc!
Love that my blood cells start their calls with "Yo, yo". Imma start doing that too.
11:20 is the answer
thanks man
Or the non-answer
Thanks
thanks a bunch
Theres actually laboratory scientist who specialize in haemtology, coagulation and transfusion that do lab testing to detect haemtolgicial disorders and then doctors in haematology that treat the haematological diseases
So, I live in Scottsdale, Arizona, and I didn't realize we had mosquitoes here for years. Then, when walking my dog with a neighbor, I realized we do have mosquitoes as she repeatedly got bitten. However, if I travel to Colorado, I'm apparently fair game there for mosquitoes. Honestly, I would love to know the science behind why Arizona mosquitoes avoid me like poison, but Colorado mosquitoes love my blood as much as the next person.
I have anemia(I've been anemic for a long time), a high platelet count, and small pink blood cells. I take ferrous sulfate for it, my platelet count is going down gradually. I need a CBC and panel before I can know if there have been any other changes.
Weirdly enough, plasma can and does change colors. When I used to donate plasma some years ago, the plasma was a pretty peachy mango color. I took no prescription medication and that was the natural color of my plasma. But the blood bank workers explained that women who take birth control pills or hormone replacement therapy often have olive green/ pea green plasma due to the medication in their body.
The first question! My daughters are B+ and I'm O+. When they were born, my blood attacked theirs and caused them to have very low hemoglobin and high bilirubin. They told me it's likely that when I had my youngest son (also B+), my body created antibodies so when I got pregnant with my twins it was prepared to attack. I never knew that this was even a thing that could happen. Thankfully they are doing well and I'm fixed so no more kids over here lol
I have a low white blood cell count. I really appreciate you bringing this up because every time I go to the doctor for a physical, they are so worried about my low WBC count. But every time I get it checked at a Hemotologist (child and adult) the numbers are consistent. They keep wanting to do tests and I am like... or this is just my normal level?
That was so informative, great lecturer! As for mosquitoes, i know that ones in Alaska would bite anyone around me, but I wasn't touched even once. But mosquitos in other countries and places didn't discriminate.
Omg I didn’t even know mosquitoes survived up there
@@beea4456 swarms of mosquitoes can kill a baby caribou. They are probably the only thing that actually thrives there.
"emia" meaning presence in blood.
Chubbyemu would be proud☺️
Great video. Loved how all the experts called here are so great with explaining and communicating!
It would be amazing if Wired can collaborate with Dr. Mike. I follow his channel and as a primary care physician, he uploads such great videos about medicine and myths and overall healthcare. Would love to see him answering Twitter questions here 😁
Basophils, macrophages and eosinophils are feeling really shortchanged here.
What always blows my mind about the blood types... humans have been around for such a longish time that I'm surprised all the time that more people aren't AB+ by now... facinates me.
Which another thing that interests me... my entire family... both on my mothers side and my fathers side are all A+... yet my daughter... O+. Confusing. Some where in my parents history... there is a recessive O that I apparently inherited... completely baffled my mind.
Liking your show... as a Lab Tech... this is awesome. Thanks.
He’s great and cute too! Bring Sanjay back for more. He reminds me of the haematology oncologist I had to see. Are they all upbeat, smart geeks?
I wish
11:17 The mosquitos 🦟
The mitochondria is the powerhouse of the cell
i remember hearing a long time ago that it had something to do with the iron in your blood. it's still not actually figured out though? if it hasn't, this would be an interesting coincidence, but i rarely get the opportunity to eat red meat anymore so i suspect my iron levels are quite low. i haven't had issues with mosquitoes in over a decade. but i used to have a ton of issues and i know my dad still has issues etc. so i always took that info about needing iron to be fact.
He explains this so well!! He’s super fun! Love to see it ❤
When I was a teenager, I went to an oncology camp for a week out in the woods every summer until I turned 18. One year (my second, I think), I was receiving chemotherapy treatments that continued during my stay. Interestingly, through the entire week I was there, I only got bit by a single mosquito. However, other years, I ended up getting more than one bite so I would assume that mosquitos can smell the toxic chemicals running through my blood. Just something I found intriguing.
Dr. Juneja is a really energetic guy with great information delivery. Wired has been doing great finding these charismatic science professionals on the program.
I just donated my plasma for the first time yesterday so the timing of this video was perfect!
Love this, Dr. Juneja is awesome. Side note: of course a hematologist is wearing red scrubs :)
This guy is great! We need more of him.
not me distracted by how charismatic he is. appearance wise and knowledge wise.
Wish this dude was my college professor I’d learn so much more
The mosquito question is answered at 11:16.
Thank youuuu
Mosquitos don't just bite some people, they ONLY bite me.
Really happy to hear about the white blood cell counts. I have a healthy but high count (the platelet donation ppl love me) After the first time I gave they told me to ask my doctor- nothing wrong, just an unusually high count especially for the area. I am not white. That probably explains it.
11:24 - Just a quick correction, CO2 is carbon dioxide, whereas bicarbonate is HCO3.
Loved this explanation style!
Incredible esse of explanation there. The mosquito question ducked me in but hooe I came away with more. Sanjay , you slay!
so wait, do the mosquitos prefer the blood with more or less CO2?
I, just a regular person on the internet, have always heard that they like more C02
As for the last question, the one on mosquitos, I doubt blood type plays a part in whether or not you will be eaten alive by mosquitos or not. My mum and I are both A+. If they ever bite her, she gets a teeny tiny mark on her skin. If I do, most times I get a bump that can be the size of a cherry tomato and can leave a mark on my skin for up to 2 months.
I read that there’s some syndrome and it’s got to do with you being allergic to mosquito saliva.
The only question remaining is: how can someone ask a question on Twitter yet cannot search on Google?
This was really interesting and the Dr. Juneja is gorgeous, so that didn't hurt. I'm one of those people who mosquitos hate. I've stood by with mosquitos on me with no bites while everyone around me get eaten up like a buffet supper.
