- Now that we've talked about your blood vessels, we're going to zoom in a little closer and talk about your blood itself. We'll start by outlining the basic components of blood -- including erythrocytes, leukocytes, platelets, and plasma -- as well as the basic process of hemostasis that stops bleeding, and how antigens are responsible for the blood type that you have. By the end of this episode, you should be totally prepared for your next blood drive.

Passed my first anatomy class, and now you're making life easier for A&P II. We appreciate you Hank! (and team)
Honestly the best page on youtube for all students around the country. And the world for the matter
Nick T world*.
JUP! watching from Holland and probibly saved me from a 3 (F)
I'm in West Africa and this is the only reason why I am not lost in class
Yup, I'm in Thailand. Crash course has saved me in soooo much.
India here...this awesome channel has spread far n wide
Coming back to thank Hank years later. I now work in healthcare and so much of my basic knowledge I’ve learned because of this crash course. Thanks Hank!
You know you're too deep into crash course when Hank starts getting more attractive as the semester goes one.
Cut appears*
Bacteria pops up: are you ready to die you cell?!?
Platelete: Hold my coagulation factor
T-cell: am I late to the party??
the human body is like one awesome team with a terrible captain at least for me
LOL tru
lol
here take my money 💰x300
Your profile is the expression for this
Watching this is a bloody good time. Hank almost red my mind.
blackmesa232323 You should go to the _pun_ itentiery.
blackmesa232323 Didn't I tell you puns run in my *blood*. Be *A positive* part of the pun community and tell the others I'm the king, also tell them not to *B negative* about the new blood dynasty. Failure doesn't run through my *veins*. Where the *bloody* hell are my pun fans? You *aorta* be a fan too.
Uzumaki Naruto claps.
Puns aren't funny your efforts are in vein.
Guy Shepard You don't have the heart to continue.
Just wanted to say thank you for your videos! I started watching your videos in 2015 when taking prereqs for my RN. Now I am graduating next week! You've helped alot with concepts.
Crash course is the best channel on TH-cam for students like me. They really make things easier to understand and thank you 😊
Passed my first anatomy class with the help of these videos and I’m currently crushing A&P II. If you’re struggling just keep watching crash course!
Thanks for helping me and all of my fellow nursing students pass A&P
my mother was rh negative and i was her second child with rh positive, they didnt know until i was born and i had to have blood transfusions as a new born, im so glad this was so well explained, i myself had a hard time understanding and explaining this to people, you guys are the best :3 love from a positive, who still doesnt know her blood type other than it being rh positive
***** why suing...? You don't know her (i assume she's a she) age. The prevention of giving anti-RhD to RhD negative mothers with RhD positive baby's is not that old...
1:50 "... a part of you that is literally irreplaceable!"
*goosebumps* JUST AMAZING INTRO!!
I rather pay double my tuition to this guy and his family rather than my professor.. He's getting me through Nursing school, this man needs raise my word
This literally summed up the entire 2nd chapter of my textbook for my Anat Phys 2 class.
I may be 4 years late saying this... but my curiosity about my low white blood cell count lead me to your videos. Your explanations and visuals really help me understand everything. Thank you so much.
CRASH COURSE YOU ARE A SERIOUS LIFE SAVER!! This channel makes anatomy interesting, easy to understand and even fun to learn. Thank you so much, this helps so much in my anatomy class.
This channel helps me so much with my anatomy and physiology tests. Hank goes over a lot of key points that my instructor did, and he explains it a little better to be honest.
Interesting fact: while the AB and Rhesus blood groups are the most common blood types for consideration with blood transfusions, there are actually dozens of different blood type groups, that all measure different things. For example, an individual can be AB, D positive, and at the same time M and N positive (MNS system), K positive (Kell system), Le^a or Le^b negative (Lewis system), and so on.
...It took me forever to memorize all of these in school :/ haha
-Nathan
Nathan Hutchcraft thanks Nathan haha found this interesting even though I'm commenting late :) hope your doing well
Nathan Hutchcraft me too, we were tested on this with so much more! Was this in med school?
This program is so awesome! Has gotten me through some tough concepts in my Ana, Phy, and Chem classes
I am officially a fan ... You've acquired a new subscriber! Thank you for this great information!
I didn't think I'd learn much because I usually get lost with all the words in biology. But this is actually very well taught. Thank you team Crash Course
How did you make this so easy? We've been going over this for weeks and it all makes sense now. THANK YOU! When I'm a pharmacist and not eating ramen I will support crash course forever
I watch every single one of Crash Course's videos, and have for a couple years now. I want to say how absolutely expertly these series' are done. I would never, ever want to listen to anyone tell me about the things I learn on Crash Course. But the hosts of each of the series' have such a critical sense of not sounding arrogant nor condescending. I don't know how the group got together, but it's one of the very rare instances in human kind's history which will remain mysterious as far as how such a truly extraordinary group of people (each absolutely extraordinary and forward thinking in their own personal way, and through their own individual lives) found each other, chose to each make a go of this, and came together in such a cohesive, consistently unique, genuine, and somehow entertainingly knowledgeable way.
I've heard the different kind of blood types described several times before but I never quite grasped it until this video with it's very helpful visual aids. Thank you.
I'm guessing all the dislikes are coming from Crips
***** Come on people, that deserves more thumbs up!
***** Ha, ha, Funnneeeee....
***** Well played
I dont get it Crips???disable people
Mark Valebcia No, dude, its the name of a gang, their worst enemy are the bloods, geddit?
The haters of the Bloods are the Crips?
This channel has gotten me 87% on my anatomy physiology exams. Thank you so so much crash course!! My number 1 study tool!
Totalmente impactada con la calidad de la informacion, la animacion y la accesibilidad. Gracias a todas las personas que hacen esto posible.
You are the reason I have a 99% in my anatomy& physiology class right now. Thank you so much for your videos!
Just one word AWESOME...AWESOME...AWESOME...
Plz make videos for Physics and Chemistry as well...
Thanks a lot TEAM CRASH COURSE...
Ah, I'm at the end of my course - thank you so much for all these TH-cams. You and your team have made studying a pleasure, actually had many laughs, and learned so much.
thank you for being here for us crash course you really made life much easier for us.
The white blood cells carry the Master Sword!
Doctor Syed believe in your strengths, believe...
There can be only one!!
I cracked up when I saw it lmao
3:16 like the master sword. You can even see the triforce on it.
I just love all of these videos! Very informative. Very helpful and well explained. Love it
I completely love all of these A&P videos!!! They are really helping me and they are so entertaining!
thank you sooooo much for this video. I was having really hard time understanding blood antigens and their relationship with doning blood. This video saved my bacon!
Did anyone else notice Rasputin at 6:10 when Hank was talking about hemophilia?
OMG TOTALLY XD
I thought exactly the same thing. Has anyone noticed Rasputin and does someone know what he has in common with hemophilia?
Jerzy Majka Hey! So Rasputin was a holy man who became associated with the Russian royal family. The tsarevich, Alexei had hemophilia, so Rasputin was called in to heal the prince. It worked, the prince felt better and so from then on Rasputin became a recurring figure in the royal family, which was VERY controversial at the time. XD
Thank you for explanation :)
Jerzy Majka Al No prob 😋
Crash course is the best channel, if not one of one ! 😮
excellent lecture with just perfect speed , my kind of presentation
loved it
Thats the cutest WBC I've ever seen! 😁😁😁
Did that white blood cell have a master sword?
I HAVE MASTER SWORDS IN MY BLOOD
+HeroHeart14z Actually, white blood cells use magic to attack, you idiot.
+XXX_ “SANIC” _XX NO ONE, FUCKS . . . WITH THE WHITE MAGE! XD
Diesel Marcus What's wrong with black mage? You racist.
XXX_ _XX it was a quote chill XD
Diesel Marcus That's sexist.
Seriously these videos are great right before I take a test. Thank you!
Thank you . You are making things easier for students and teachers too .
I love that little reference to Rapsutin when talking about blood clotting. I'm studying the Russian Revolution
Thanks Crash Course for doing these videos, I like all you guys videos!
I visited this channel for the first time and now i can say that it is the *bestest* video i watched today
The Leukocyte with the Master Sword lol
Don't read this you have got a lot of studying to do...
Hank is he best you've helped me with a lot or stuff in my biology class thank you! Your awesome :)
great video!! just summed up everything I've learnt for my test!!
is that rasputin in 6:14?
Lol that leukocyte was holding a master sword 🗡 😂😍
This is bloody awesome as usual. Thanks Crash Course!!! A great big 👍👍’s up!!!!!
Idk what it is but whenever I get sleepy studying all I have to do is look up a Crashcourse video and it wakes me up and gets me pumped to study some more!
O- here. been giving blood since I turned 18
I like the fact that the leukocytes has the master sword from The legend of Zelda series
To add on, the endothelium is the single layer of squamous endothelial cells that line the interior surface of blood vessels and lymphatic vessels. Thank you for the amazing videos Crash Course! Great way to make use of the time I have on my hands right now.
Love videos like this with illustrations! 💵💵🫑💵🫑
The best man ever and the best show ever...for any student it is a time savier... thus mean MY life savier which end to be ..YOU my real hero. real thanks for you and also for donors thats keep it alive.
"its just a body" but if you know deeply how the system work.... truly God has put so much effort ❣️🥺
Always wondered what the blood types meant. Very informative, as always.
definitely my hero for mention true blood haha! such a nice page for learning anatomy and physiology
When you’re watching in March 2020 where blood drives are shut down because of the coronavirus
"The property of Hank!" Hah!
CrashCourse is really awesome... Especially the animation part.
I really enjoyed this, thank you.
Why am I paying thousands of dollars for a college course when TH-cam teaches better..
Was that Rasputin over Hank's Shoulder?
Four years too late, but the reason is because the Romanov family hired Rasputin, a holy man, to treat their son Alexei's (the heir of the throne of the Russian Empire) hemophilia. It worked, surprisingly. No one knows what he did exactly (he kept it secret because he wanted a reason to stay close to the family), but it is suspected that he removed something that was making him more ill (can't remember what) from his environment.
Thank you...well explained, well understood.Bless!
This series has been so helpful to my summer class at Rutgers! Thank you!
+Shannsy 95 kik?
"now you're bleeding all over your breakfast.."
Hanks hair tho
This guy explains it so well!!! Thanks
Crash Course is my favorite!!!! Thank you!

Brawndo - Its got what plants crave. Its got electrolytes!
OwenBruch22 Water's what they put in toilets and I ain't never seen a plant grow out of a toilet!
Electrolytes are just any material that ionizes when dissolved in an ionizing solution (like water)
SubscribeToSyndicate You think Einstein walked around thinking everyone was a bunch of dumb-shits? Now you know why he built that bomb.
Bob Hope What?
SubscribeToSyndicate They are all quotes from Idiocracy, it's a movie.
*Hank thanks for information, btw makingvthese videos actually help me in my studies*
Nice work.
8:50 actually the antibodies from the mother attack the baby, not the other way around, in most of the cases. To answer the obvious question of why on the Rh group matters in the case of mother to fetus blood contact it is because the antibodies against ABO antigens do not cross the placenta but Rh antibodies do.
I scrolled *so far* to find this comment!
"Your blood is the one component of your body that we haven't figured out how to reproduce synthesize or imitate."
That's great. It might be more impressive once we've got a better handle on Immunology.
I think he was talking about the brain there 😂
Anyone else's mind blow when he said blood was a type of connective tissue?
Damn. Crash course is much more easier and faster to understand than the 4 hour lectures I have everyday for A&P2.
I like crash course but I think the host speaks too fast. I'm a slow learner so the rapid speaking kind of confuses me. Other than that, I really do appreciate this crash course :-D
Playback speed 0.75? Makes Hank sound like he was dropped as a child tho.
Just slow the speed down easy fix, also try professor dave explains!
Blood trees would be freaky af... o.O
Very informative. I love the little Rasputin figure shown at 6:15, nice historical tie into Hemophilia ;)
Thank you so much, this is very helpful
Wondering how this is blood part TWO…
***** No, because the thumbnail still says 'Part 1'
Whos here at 2019?
yassss
Meeeee
Ive never watched all the way through the end of any crash course video where he says who wrote the script and who he consulted so basically this whole time I've thought he was the smartest person on earth and knew a ton of random topics in depth
Very helpful videos!! I really appreciate!
Hank said "flavor" when he was referring to blood type...HA!
LAST!!!11!!
You have a nice way to send your message .. go on👍👍
This page saves my butt every week before my exams (i'm in an accelerated A and P program this summer and I'd flunk without this page). Thank you!!
O- Master Race reporting in
Michael Spencer Until you need a transfusion, and then you wish you were AB+.
