Question

why do humuns become pale after death?​

Answer 1

Answer:

Livor mortis, or lividity, refers to the point at which a deceased person's body becomes very pale, or ashen, soon after death. This is due to the loss of blood circulation as the heart stops beating.

Answer 2

Answer:

There are several signs that a body has begun its process of decomposition, Goff explains. Perhaps the three best-known ones, which are often cited in crime dramas, are livor mortis, rigor mortis, and algor mortis.

Livor, rigor, and algor mortis

Livor mortis, or lividity, refers to the point at which a deceased person’s body becomes very pale, or ashen, soon after death. This is due to the loss of blood circulation as the heart stops beating.

Goff explains, “[T]he blood begins to settle, by gravity, to the lowest portions of the body,” causing the skin to become discolored. This process may begin after about an hour following death and can continue to develop until the 9–12 hour mark postmortem.
