Which Body Part Remains Unchanged From Birth To Death?

The body’s various organs and tissues exhibit varying degrees of post-mortem viability. Immediately following cessation of breathing, the brain and nerve cells are the most vulnerable, with their survival lasting only a few minutes without oxygen. Subsequently, the heart ceases to function, followed by the liver. The kidneys and pancreas, however, exhibit a slightly longer window of viability, lasting for approximately an hour.

Remarkably, some parts of the body can remain alive for more extended periods after death. Skin, tendons, heart valves, and corneas, for instance, can remain viable for up to a day after death. This extended post-mortem vitality in certain tissues has implications for organ and tissue donation, as well as for medical research and transplantation purposes.
