The Composition and Function of Blood

Of course we all know what blood is, and everyone has had at least a minor injury involving blood. But what is it exactly? What's it made of? What does it do? Why do we die if we lose enough of it? Let's check out each component of blood now, on both the cellular and molecular level!

Hey Professor Dave! Just wanted to thank you for the videos. It's really nice to have a single channel that explains a whole lot of stuff! I personally enjoy learning about a variety of things, so when I'm a bit tired of one specific topic I go read about geography, or biology, or something else.
It's nice to learn by reading but it's even better hearing someone who understands the stuff explain it, so thanks!
"But what is it exactly? What's it made of? What does it do?" that's legit me earlier today in the bathroom trying to remember what Van der Waals force is haha

Ma dude P.Dave comin through with another banger. You helped me pass Chemistry, A&P I, and Microbiology with A's, and now your videos are helping me study for A&P II. Thanks for all your hard work and straight forward and easy to understand videos! You make learning these somewhat difficult topics so much easier!

By far Theeee Best blood histology Video on RUclips hands down 🙌🙌🙌

[@thimbleteeth]

I want to make a game with my own spin on the concept of “what if the human body was just a little place with a bunch of little guys in it” focusing mainly on blood cells. This video is incredibly helpful to me in my endeavors, and it is also simply very nice to be able to learn more about anatomy. Thank you, Professor Dave! :-)

[@monaoconnell5650]

Great! Very informative and easy to understand!

[@conman1395]

4:06 One thing I emphasize to my MCAT students is that there is a difference between oxygen molecules and oxygen atoms. Oxygen is diatomic in gaseous form so hemoglobin contains 4 oxygen molecules (O2) but 8 oxygen atoms (O).

[@orlaundrapryor7310]

Thank you so much you explained this information so well. I was getting excited because it was all coming together in mind. Please continue to provide such great content.

Dear Emmy, my soon to be born grand daughter ... if you have gotten this far into these educational videos, then my influence upon you was positive. Please, by all mean, continue on. There are also all those educational videos by AronRa, Neil deGrass Tyson, and so many more I will have probably told you about by the time you perhaps, someday see this comment?
Love ya kid,
grandpa
