Capillary Exchange : Bulk Flow (Filtration and Reabsorption)
Have you ever wondered how nutrients and oxygen makes it to the cells and tissues? What forces drive the flow of substances into and out of the capillaries? Or maybe you're really just struggling with the concepts of bulk flow and different pressures such as Capillary Hydrostatic Pressure, Blood Colloid Osmotic Pressure, Interstitial Fluid Hydrostatic Pressure, and Interstitial Fluid Osmotic Pressure. Then, you've come to the right video!
In this video, I will break down what happens in capillary exchange (exchange between the blood and interstitial fluid) and the different pressures that allow the exchange to happen. I will describe each pressure and how it changes as blood flows through the capillary bed. By the end of the video you will understand how capillary exchange, specifically, how bulk flow occurs. And, you'll also learn about different pressures, that may have been overwhelming to learn, but now you finally understand them!

You forgot to mention the throat and the nose bc every itches
Thank You Maam,Radhe Radhe Radhe-Shyam, 🙏।
You’re welcome! So glad that it helped!
You மிஸ் r
And it all came from nothing!!! 😂
3:05 Potential = looks good on paper 3:15 many studies = no approval 3:23 Potential = to solve challenges developing vaccines Looked good but it wasn’t . .. many studies and it was never safe enough to get approval … we push it to the public then a new precedent will be set that shortens time and lowers safety standard ..
I have asthma and sometimes me and my sis share inhalers if we run out
Thank you for this.
So glad you liked it!
i had Asthma before i recovered without a inhaler
Sometimes with mild cases it may be possible, for others, medication is absolutely necessary.
@@DrVanessa Okay
I heard ears can be just as identifiable as fingerprints cause no two people have similar ears.
YES! Crazy right?? There was a recent study published on that: www.sciencedirect.com/science/article/pii/S1286011523000620?via%3Dihub
❤ nice
Love from 🇨🇦
Great simple video
Thank you!
Can u show super and inf oblique mov
These muscles aren’t on my model, but they wrap the eye, one on top and one on bottom. They allow the eye to move in a circle. So the superior oblique allows the eye to move towards the nose, towards the outside and down. The inferior oblique allows the eye to move towards the nose, toward the outside and up. I hope this helps! I can work on making a short with this, my model just doesn’t show these muscles.
@@DrVanessa sure 😊 this helps... Thanks much for responding
I HAVE SALMONELLA‼️‼️‼️‼️
Great Initiative, Add more value in your videos please.
Thank you! My longer videos have much more information and value. Still trying to figure out how to really make the shorts have more value with only 15 seconds.
It means left part of brain control right side of body and vice versa isn't?
That’s different than vision, but yes, in a similar way, the left side of the brain does control the right side of the body and vice versa.
Anyone who says asthma medicine doesn’t work has never been saved from the brink of death when they finally got their inhaler.
Asthma medication is amazing in how fast-acting it can be to help open up the bronchioles! Sometimes, it takes a bit of work to figure out the right preventative type of asthma medication.
thank you so much!!
You’re welcome! I’m glad it helped!
Love from New Delhi❤
Happy to have you here! Glad you are learning!

How much time does it take to create resistance against antibiotics please must replay i am suffering from fungal infection. My doctor recommended me same antibiotics again again its been 2 months ?
Fungal infections are difficult to treat. I am not a medical doctor and do not offer medical advice. If you are not getting better, you need to see your doctor again or perhaps get another opinion.
They cause diarrhea
They can! Which is why it’s also important to take a probiotic, but space them apart so they don’t counteract the work of the antibiotic.
Where are you from ❤
I’m in the US.
Allah bless you I felt very comfortable to see your video. Thank you so much
Thank you! I’m glad you enjoyed it!
Thank you for explaining it very well

Are this antigens different from the antigens present in human RBC?
Antigens are things that the body recognizes as foreign. We usually think of them as pathogens, viruses, bacteria, etc. that come into the body, that is not a self protein. However, as you pointed out, antigens are present on RBCs. This can make it confusing. This is because the body CAN recognize them as foreign, and have antibodies against them. The difference is, the person who actually has the antigen on their RBC, it is really not an antigen to them because it will be a self protein, but can be an antigen to someone else. This was all found and named before our understanding of the immune system and antibodies and antigens. But, because some people can recognize those cell surface markers as foreign, they have been called antigens. Check out the video I link here, that will show you more. Hopefully, that will help clear up the confusion. And, reach out if you have any more questions! ua-cam.com/video/p6xoRJ3rWpQ/v-deo.html

so it's that bad wooow
Yes, it can get pretty bad! Could even lead to pneumonia if the individual suffers from severe asthma.
Will it ends up with scar?
@@annsherlyantony6781 depending on how long, ex, chronic asthma, etc. and severity of tissue damage, yes, some areas can scar.
Clinical trial conducted at the Mater Hospital, Brisbane, Australia Buteyko breathing techniques in asthma: a blinded randomised controlled trial. Simon D Bowler, Amanda Green and Charles A Mitchell - The study was carried out from January 1995 to April 1995. - This study uses the gold standard of trials (blinded randomised controlled trial). - The asthma patients were taught Buteyko the proper way, by actual Buteyko instructors. - Quite a large group of asthma patients were taught. Buteyko group: Respiration after 3 months (l/min): 9,6 Bronchodilators after 3 months: 96% less Inhaled steroids after 3 months: 49% less Reduction of symptom scores after 3 months: 71% After 6 weeks quality of life for the Buteyko group improved with 54% Control group: Respiration after 3 months (l/min): 13,3 Bronchodilators after 3 months: 7% less Inhaled steroids after 3 months: remained the same Reduction of symptom scores after 3 months: 14% Additional results from the trial: 1: Asthma patients have lower CO2 values than the normal population The study showed a big difference between end-tidal CO2 values of asthma patients and people without asthma: the normal group had an average end-tidal CO2 of 43 mmHg whereas the asthma patients had an average end-tidal Co2 of 34 mmHG. That's a big difference in CO2 levels which agrees with Professor Buteyko's claim that asthma is caused by low CO2 values. 2: Asthma patients breathe more than the normal population Minute breathing volume was higher in asthma patients than in the group of normal people (without asthma). This agrees with Professor Buteyko claim that overbreathing (hyperventilation) causes asthma. 3: Asthma patients who practice Buteyko need less medication as they become better at Buteyko The finding that the relative reduction in beta2-agonist medication was related to the proportionate reduction in minute volume with Buteyko is extremely meaningful. This really means that the more progress asthma patients make with Buteyko, the less medication they need. This is such an important finding that the title of the study could well have been: "Asthma patients who practice Buteyko Breathing need less medication as they become better at Buteyko"! 4: Buteyko does what it promises: change breathing habits and reduce disease symptoms The finding that Buteyko lowers the average minute breathing volume from 14 liter/min to 9.6 liters/min proves that Buteyko Breathing really does significantly change breathing habits. The finding that asthma symptoms went down by 71% proves that Buteyko does improve health and reduces chronic disease symptoms. So these two finding combined together in effect prove that Buteyko Breathing does do what it promises. 5: Buteyko reverts hyperventilation The finding that Buteyko lowers the average minute breathing volume from 14 liter/min to 9.6 liters/min is also a highly significant finding for people suffering from hyperventilation. Those suffering from hyperventilation can learn and practice Buteyko Breathing to reverse and improve their hyperventilation symptoms. The Buteyko group experienced a significant reduction in the need for reliever medication and steroids, along with a greater improvement in quality of life. If an "Asthma Pill" came on the market today that would achieve such results, it would be prescribed to all asthmatics tomorrow. On a side note: “The control group showed little change in medication and quality of life despite being taught the conventional breathing exercises (relaxation techniques and abdominal breathing exercises which did not involve hypoventilation) that continue to be the mainstay of treatment in hospitals and clinics. It is interesting to note that half the control group was later taught the Buteyko breathing exercises (exercises in which subjects reduced the depth and frequency of respiration) and the results from this group were consistent with earlier findings.” References: Buteyko breathing techniques in asthma: a blinded randomised controlled trial.

Depending on the type, they can. Broad spectrum antibiotics can wipe out our normal guy microbiome and cause gastrointestinal issues.
