Is it just the organs, or things like blood and hair too?
In: Biology
All organs have the potential to be used: heart, lungs, kidneys, liver, sections of bowel, skin, eyes, etc. Pieces of them as well. That doesn’t mean any or everything will be used. It’s a very stringent process.
Blood would never be used. There is a very strict process to use blood. Blood that is in a dead body isn’t much use, especially when there are living donors who can give blood.
Anything that’s viable to use and in good condition. Lets say you die of a heart attack, or heart failure, then obviously they won’t use your heart.
If you’re an organ donor, it also depends if you sign up as a tissue donor as well then they might use things such as skin.
The lenses from eyes can be transplanted to help someone see. It’s possible that a scalp transplant could give a head of hair to someone who was severely burned. Skin transplants are common, as are bones (though usually not whole ones) & tendons/ligaments. Heart, lungs, kidneys, liver, & blood vessels are common.
Not sure about stomach, intestines, muscles, bone marrow, or pancreas.
Hair could be cut off & donated to make a wig, but that’s not usually thought of as “organ & tissue donation”.
