Man... about 800$ per credit for a 4 credits physiology course at my university, and I end up self learning here (with more details from the book) Such a waste of money :P Thumbs up to the whole team, the videos are amazing! You'll have my forever gratitude if I get accepted in med school.

Mr. Hank Green, a very big thank you. I am a fourth year medical student that has forgotten all my basics over the break and this whole series is exactly what is giving me hope again and giving the bigger picture you often lose with inactivity. Thank you so much for all the videos over the years. From my A-Levels to my MBBS degree you have been there every step of the way!

What's weird is where the CO2 comes from. We know it's a waste product, sure, but a product of what? Well, combustion, in a sense, although we call it cellular respiration. Your cells are oxidizing stuff, mostly glucose, and turning it into ATP. The citric acid cycle that they use to do this produces, as byproducts, CO2 and water. We can use the water, but we send the CO2 to the lungs to be exhaled. So after you eat something, your body burns it, and then you breathe it out. So weird.

@shantasedhain7830 8 жыл бұрын

+Matthew Prorok not just citric acid cycles and the byproducts are not just water and CO2 . so after we eat something we just don't breathe it out. excretion too is there and well CO2 maybe because for the natural exchange of gases(oxygen and carbondioxide exchange between animals and plants to take place). You're just taking example of specific systems and making things more complex(but calling it weird) without understanding the complexity within these systems.

Good video as usual. One thing which I suspect was beyond the scope of the video but which it sounded like you commented on was the process by which hemorrhoids are formed. It sounded like you suggested that these are due to varicose veins, while they are actually due to the formation of arteriovenous anastomosis. Granted both varicose veins and arteriovenous anastomosis are due to increased pressure in the area which is what I suspect you meant

Question: does every cell have to come into contact with a capillary to receive oxygen? If not, does a cell get it's oxygen from an adjacent cell? On a side note, this series has made me almost, *almost*, understand where creationists are coming from. Living bodies are freakin' amazing.

@uploader109 9 жыл бұрын

Yes, cells exchange nutrients and waste between each other. That's how cartilage, the tissue with the least blood vessels, keeps itself alive and healthy despite not receiving thorough blood circulation.

@greg77389 7 жыл бұрын

What's that got to do with creationism? Try *intelligent design.* Young earth creationists deny evolution so their position is pretty much invalid... Intelligent design on the other hand simply argues that complex life was designed by something intelligent rather than solely being an extremely improbable byproduct of an unintelligent event or series of events. The theory of intelligent design does not deny evolution.
