re: Why are organ donor’s medical records private if they willing chose to donate their body?

Being an organ donor and donating your body to science are two very different things.

Organ donors allow folks to use their corneas, heart, kidney, etc for transplants, I’m signed up for that.

Donating your body to science can be anything from being a cadaver in med school for anatomy work to having your parts sold online for whatever use. John Oliver recently did a segment on this. A lady donated her son’s body to science to save on burials expenses, and a reporter was able to buy his spinal column for a few hundred bucks. There is an odd marketplace for parts.
