eli5: If someone dies in a hospital, why can’t we just give them organs and blood ASAP?
In: 0
My knowledge is limited as I’m only just beginning to get a degree in physiology. But from what I’ve learned, the most important thing to maintain in the body under abnormal conditions is blood glucose levels because glucose can be broken down with the help of oxygen to create ATP, which is energy. Without ATP, our organs can’t perform various functions and in about 4 minutes, we can have permanent brain damage if there’s no oxygen and death can occur in 4-6 minutes. The brain controls everything. Without the brain working, the blood vessels that supply oxygen in our blood to all the organs will no longer be functional and our organs will die. If someone died, you’d need to replace their brain, and brain transplants to my knowledge aren’t possible. I’m not sure if something I said was inaccurate but here are my thoughts on why we possibly can’t just replace organs and blood.
