Which organ of the body dies first?

After death, the brain is the first organ to "die" because its cells rapidly perish from lack of oxygen within minutes, leading to irreversible cessation of function, while other tissues like skin, tendons, and even some organ cells can remain viable or show activity for much longer periods, up to days.
