Not exaggerating when I say that this channel has saved my grades so many times! these kinds of videos also saves my adhd ridden brain the excruciating pain of reading and re-reading the same pages for hours
The kidneys are like the pool maintenance guys at the Hilton: constantly checking pH, adding trace chemicals as needed, ready to open the floor drain if necessairy. Good work guys.
Me: "I need to study for this Health test" Me throughout the video: "OMG I FINALLY KNOW WHY BIRDS DONT PEE" (Future me during my test) "Whats the Excretory System again?"
Thanks for making these videos! I am a college student at Queens College taking Anatomy and Physiology. My professor seriously sucks. His lectures are 3 hours a week where he rants about being a failed doctor. He gives us powerpoints of notes that are on average 90 slides long and he tests us on information that isn't in our text books. I've been trying to teach myself all the body systems. Your videos are a little more basic/general than my class but they are helping me study. I apreciated the discussion of nephrons and background on Henle in this video. You do a great job of highlighting the important parts of the body, explaining their significance and making it memorable so I won't forget on the test. lol. Thanks! I'm sure I'll be watching more of your videos in the future.
i see these comments about tests on all these video. Is this what is actually covered in highschool? I never took biology im just watching cause i find it interesting :)
i've taken biology twice (once in my old school, and currently in the one I'm attending at present) and this is for human biology rather than general biology, although I'm sure he also does videos for general biology. (biology is my favorite subject, in case you couldn't tell)
i'll be honest. many episodes ago i was no longer able to keep up and am now just listening cause i like people talking to me plus its nice seeing the colorful pictures.
Ok Hank, I seriously have to doubly thank you for producing this series and to all of your crew for making it. I'm studying to take a HESI-ADN test this Saturday, which is an 8.5 hour test that covers math, reading, and something like 6 different sciences, including basic biology, anatomy and physiology, chemistry, etc, and this is helping me gain a better understanding of some of these systems than I did from my actual biology classes. It's a phenomenal study tool, and I'll be recommending this to all of my student friends and my teachers to share. I can't say enough how great this series is.
94% across the board. Except for math, in which I got a 98. Study the flashcards for the vocab online, too. All these videos helped, especially the chemistry ones.
Rhonda Lee I got a 94.something, but I studied these videos. All of them, the whole playlist. Take care to note the chemical reactions going on. Also, anatomy directions, at least a little.
Study from the textbook... No quizzes/hw grade. Only one major test for this unit which involves random super-detailed info on all eleven main human systems......... You saved my life, Hank+CrashCourse!!
I like how you explain that medulla is marrow and that the proximal convoluted tubule is the tube near the beginning that is windy. That helps me actually remember all the complicated words. Thanks hank!
this is my first time watching one of your videos and all i have to say is: you ROCK! you're amazing, keep on doing these videos cs people like me (the ones who learn more by watching than reading) need you!!
Your videos are awesome, love the humor, love the colorful graphics and the information is concise but covers the important points. I used your videos to study for my massage therapy exam instead of reading the books....Keep doing what you do!!!!!
I'm about to start college this year, with a major in biology. I took AP bio last year, and I took anatomy and physiology. A few days before my AP exam I was trying to study but couldn't focus on my text books and notes, so I decided to watch some of the crash course biology videos (sadly there weren't as many at the time). They were so much easier to study from than my notes, and I got a 5 on the exam! I'm now reviewing the videos so that my brain is ready for college. Thank you Hank!
Also, I though it would be kind of inefficient if we did filter out every single drop of filtered water. Let's use an analogy to understand my statement: when you have a fresh new bar of soap, and you use it, there isn't as much soap as there was, but there is still soap. You keep using the soap until it's at that phase where it's small and it will start to break apart. so you get some more soap. So if you didn't get that analogy, basically what I'm saying is that we can reuse the water in our bodies because it's not so dirty that it will hurt you.
i was watching this in class just now, and when he said the cradle of filth cover band joke i started laughing... but no one else did in my classroom... was pretty awkward.... sometimes it really sucks to be a metal head
Am I the only one here who has just been watching and trying to understand these biology videos for fun? I love crash course that much. But this has definitely been one of their hardest series to sit through
Always a fan of crash course. I always watch the corresponding videos before starting my A&P chapters. It gives me a basic starting point so that while learning we already have an idea what they are talking about.
I have taken a great deal of biology courses, both in high school and university, and this is the best -and possibly only- description of the excretory system I have ever heard. Until now, all I've ever heard about it is that "kidneys filter your blood which leads to your bladder". Once again, free Crash Course >> ludicrously expensive university education. Nicely done, Professor Green!
I like the way you say 'Lupe of Henle', because you can actually tell it's 3 words. When I did this in school my teacher pronounced it like 'Lupofenaline' and for ages that's how I spelt it.
Thank you so much. As someone with a biology professor whom I'm pressed still cared enough to come to class today, you are the reason I have a chance of passing this test.
I have my Biology mock exam in 11 hours and I'm just discovering these wonderful videos! The graphics are so simple yet informative and I'm loving the extra little impressive and interesting facts or bits of historical information that I can throw at my lab partner to make him feel inadequate ;) Awesome videos, I'm hoping these will save my ass for these mock exams, and get me the grade I need for Uni on the real ones. THANKYOU!
"Why are we so bad at naming things?!?!" And, Proximal Convoluted Tubule is one of the better ones. It's way better than: Substance P or Intrinsic Factor -- names that tell us nothing about their location, function, or chemistry. Great question. You could start a blog about it.
From one (future) biology teacher to another, I'd like to commend you on your continual explanation of latin and latin-based terms. So many teachers just pass that over, but it's important to understand the language of science, and you do an excellent job. Thanks!
Sweat is primarily to cool us down (thermoregulation), but because it contains small amounts of metabolic waste products (like urea, as well as water and mineral salts), sweating is considered excretion. That means that the skin is considered an excretory organ. Hope I've explained that well enough :/
"From Your Heart to the Toilet..." sounds like my last relationship........ xD
same
+Amber a. lmaoooooooooooo
Lmao .....nice
never had one. ahh the life of a nerd can never get a date.
Nel's Wolf lol not for me tho nerd and I have had gf

"Well, honey, when a Glomerulus and a Bowman's Capsule love each other very much..."
Convinient.

How to study for bio tests- watch these videos, read your notes, understand things for the first time in forever.
Facts
😂😂😂😂😂😂😂😂
Me: "I need to study for this Health test"
Me throughout the video: "OMG I FINALLY KNOW WHY BIRDS DONT PEE"
(Future me during my test)
"Whats the Excretory System again?"
Lol
great breakdown! very helpful. wanted to get a quick review before we cover this in class.
Salty Medulla is a good band name.
+Lord GabeN So is Loop of Henle.

CUNY?
More basic than these videos? My god, university level biology must be hell!
I love this guy. he's awesome. he's funny and he loves what he talks about. I listen to him in the car. studying anatomy made fun!!
my teacher showed this video to my science class. i completely started fangirling.
Exactly! That's really the reason why I was fangirling! And plus hank too!
lol !!!!!!!!! btw like your username
"Mango-sized kidneys"
Great. Now I want mangoes.
mulimah29 LOL me too ~!
"Which empties out wherever you point it!" LOOOOL.
😂😂😂

my kidneys heard this lecture and now they are offended
My gallblader is particularly upset.
You could even say that they are.... Salty.
yup very
Thank you! Thank you for actually making these subjects sound as interesting and as fun as they really are!
Was a fan during high school
Am still a fan now that I'm in college...
This still helps. A lot.
Keep making these awesome videos. I need them.
6,633 people passed their tests
114 failed their tests
Let's hope I'll like this tomorrow
That has increased to
7,019 passing
120 failing
as of today

10000 passed, and 203 failed now.
This channel is a gosh damn text book especially for Highschool level Humans and Social biology.
i'll be honest. many episodes ago i was no longer able to keep up and am now just listening cause i like people talking to me plus its nice seeing the colorful pictures.

Kate Turner how did you do .. I take mines this Saturday and I agree this totally helps me understand better
94% across the board. Except for math, in which I got a 98. Study the flashcards for the vocab online, too. All these videos helped, especially the chemistry ones.
Kate Turner I took it nov 12 and made an 72 on a and p .. what did you get on that section and what did you study ??
Rhonda Lee I got a 94.something, but I studied these videos. All of them, the whole playlist. Take care to note the chemical reactions going on. Also, anatomy directions, at least a little.
Study from the textbook... No quizzes/hw grade. Only one major test for this unit which involves random super-detailed info on all eleven main human systems......... You saved my life, Hank+CrashCourse!!
Ur the best and got me a hundred on my science essay for the 5 systemsI'm about to donate for pure comedy
this chanel is sooooooooooooooooooooo good ! fun and knowledgable at the same time!!! I love it
I love watching this show at half speed because he sounds drunk and its entertaining XD
+Aliza canjura stupid question, but how do u put it in half speed? He speaks a little fast. It would help! thanks
+Shahjahan Ali Under the settings cog, you have different options and one of them is speed. Hope this helped!
+Aliza canjura thank you so much for the tip i died
I like how you explain that medulla is marrow and that the proximal convoluted tubule is the tube near the beginning that is windy. That helps me actually remember all the complicated words. Thanks hank!
this is my first time watching one of your videos and all i have to say is: you ROCK! you're amazing, keep on doing these videos cs people like me (the ones who learn more by watching than reading) need you!!
And this is the first time I've ever heard it called the EX-kruh-TORY system. Hank's accent is always an adventure for me.
Your videos are awesome, love the humor, love the colorful graphics and the information is concise but covers the important points. I used your videos to study for my massage therapy exam instead of reading the books....Keep doing what you do!!!!!
I am glad my biology teacher showed me Crash Course videos
"Don't do this, but if you were to unravel all of your nephrons..." Oh, phew. Thanks for the warning, I was just about to.

Thank the universe for CrashCourse. All these convolutions have been cleared.
11:04 "Empties out, wherever you point it."
HAHAH
How do you dislike something this awesome
i was watching this in class just now, and when he said the cradle of filth cover band joke i started laughing... but no one else did in my classroom... was pretty awkward.... sometimes it really sucks to be a metal head
That's amazing. I would have laughed with you xD
This is by far the most comprehensive, accessible, fun and effective educational material I've ever seen. Keep up the good work!
This is going to help me pass my IGCSE's!
Am I the only one here who has just been watching and trying to understand these biology videos for fun? I love crash course that much. But this has definitely been one of their hardest series to sit through
My teacher toldo me to watch this video, its incredible
Always a fan of crash course. I always watch the corresponding videos before starting my A&P chapters. It gives me a basic starting point so that while learning we already have an idea what they are talking about.
The white stuff on my car isn't technically bird poop. Mind = blown.

Nicely done, Professor Green!
youve made studying for midterms a lot easier for me
I learned more in the twelve minutes I spent watching this video than I did in the two weeks spent sitting in class. Thank you so much!
HAHAHAHAHA slow the video down to 0.5 speed!! You won't be sorry :D
Try it in double time too.
GAHAHAHAHAHA.DIED.
How?
That was just too funny. At 0.5 speed It sounds like Bill Cosby is teaching me about the urinal system
lol
If I ever do anything of merit with my degree, I will mention you Hank.
This is so helpful. I will save up and donate money to you soon.
hank and his brother should do a competition to see who can remember the periodic table song from Asap Science and post a video of them singing it.:D
Hank. Mad respect for repin the 406. MSU student and Montana native here
Here because of school check
Im in my last year of school and this channel is going to save my leaving cert! THANK YOU HANK!
must watch before exams :-)
I like the way you say 'Lupe of Henle', because you can actually tell it's 3 words. When I did this in school my teacher pronounced it like 'Lupofenaline' and for ages that's how I spelt it.
'Also the name of my Cradle of Filth cover band.' lol'd really hard
Thank you so much. As someone with a biology professor whom I'm pressed still cared enough to come to class today, you are the reason I have a chance of passing this test.
This helped soooooo much :D
I have my Biology mock exam in 11 hours and I'm just discovering these wonderful videos! The graphics are so simple yet informative and I'm loving the extra little impressive and interesting facts or bits of historical information that I can throw at my lab partner to make him feel inadequate ;)
Awesome videos, I'm hoping these will save my ass for these mock exams, and get me the grade I need for Uni on the real ones.
THANKYOU!
I love ur videos. u have a good, interesting way of saying it without putting me to sleep! ^_^
I watched this while finishing my lunch. Highly recommended.
you are too amazing. this is so helpful ^^
This was a great way for me to learn the excretory system for the MCAT, which had been giving me all sorts of troubles up until now. Thanks so much!
why didnt you include coiunter current mechanisum..any way
A LOT OF THAnKS
Thank you for helping me with O level biology. I love you.
Hank is such a bro
Agreed, just take a physiology or anatomy class this is like a nice refresher.
AP exam tomorrow...
yeah, fuck
Studying like crazy
i see i am not alone. good luck everyone!
much terrified
This is the first I'm learning of any of the systems outside of psychology, so yeah, I'm screwed
"biology and history videos" its nice to be there during all the development
"which empties out wherever you point it" LMAO! I know what you mean. \-)
I've got a homeostasis test tomorrow and this was perfect review. Thanks :D
He's faster than eminen
You're right gal
Happy there is peapol like you that share there knowledge whit others for free thanks
"Why are we so bad at naming things?!?!"
And, Proximal Convoluted Tubule is one of the better ones. It's way better than: Substance P or Intrinsic Factor -- names that tell us nothing about their location, function, or chemistry.
Great question. You could start a blog about it.
its amazing when you realize how complicated the human body and how it works and for what purpose we were created
This is the first video I've ever watched that you've talked so slow
Thanks for the video.
Your explanation was very clear and entertaining
2 AM is a great time to be crash coursing on pee.
oh joy xD
My only time to watch you, Hank,, is on my lunch break.
water reabsorbtion, shmarter reashmortion. do you be what i do all day? lol all day long!!!
Thank you for this video, it's really helpful and it's going to help me get a good grade on my ib biology test tomorrow.
Watch 2:00-2:20 at 0.5 speed, im crying
nice
Haha I'm using this to study for tomorrow's ib Biology final !
This guy is a genius... I think he's secretly Spider-Man.
If I ever somehow become a teacher; these will be a valuable part of my teaching toolkit.
Cradle of Filth cover band? LOL! Awesome how he actually knows about them.
MINDBLOWN!! Listen at 2.0, Hank speaks just as Jesse Eisenberg!
Hi I'm in seventh grade dis is my homework =3
There was an FRQ on my AP exam today about alcohol and urine output and I swear I last cried I was so happy because I watched this last night
AP Bio anyone?
From one (future) biology teacher to another, I'd like to commend you on your continual explanation of latin and latin-based terms. So many teachers just pass that over, but it's important to understand the language of science, and you do an excellent job. Thanks!
Anyone has exams tmr ?😂😂🙋🏻🙋🏻
Maggie Li yep
today infact!!!
O level lmao
me
Lol I do !xD
A&P exam next weeeekkk binge watchhingg uuuu thank YOU
wait so why is sweat connected to the excretory system?
Sweat is primarily to cool us down (thermoregulation), but because it contains small amounts of metabolic waste products (like urea, as well as water and mineral salts), sweating is considered excretion.
That means that the skin is considered an excretory organ.
Hope I've explained that well enough :/
THANKS A BUNCH none of the other vids and websites were helpful that much THANKS XD
Leo theLion12 You're very welcome :)
XD
The membrane homeostasis!
Hank you are saving my life right now x
Just leave him alone LADSS!!!!
I've found this and a few other Crash Course videos unbelievably helpful, thank you!
Unit exam tomorrow...lol
Thank you for making the subject interesting
