The stages that follow shortly after death are: Corneal opacity or "clouding". Pallor mortis, paleness which happens in the first 15–120 minutes after death. Livor mortis, or dependent lividity, a settling of the blood in the lower (dependent) portion of the body. Algor mortis, the reduction in body temperature following death.
Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized : apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to characteristic cell changes ( morphology) and death. [2]

Algor mortis (from Latin algor 'coldness' and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched. This is generally a steady decline, although if the ambient temperature is above the body temperature (such as in a hot desert ), the change in temperature will be ...
Thrombus. A thrombus ( pl. thrombi ), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.
Programmed cell death ( PCD; sometimes referred to as cellular suicide [1]) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. [2] [3] PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle. For example, the differentiation of fingers and toes in a ...
