Intro to Thanatology

Thanatology

the study of death and the processes associated with it, including the social, psychological, and cultural aspects of dying.

Death

the cessation of all biological functions that sustain a living organism, marking the end of life.

ATP (Adenosine Triphosphate)

the primary energy carrier in cells, crucial for cellular processes and metabolism.

Pallor Mortis

the post-mortem paleness of the skin, occurring due to the cessation of circulation.

Algor Mortis

the cooling of the body after death, which begins shortly after circulation stops and continues until body temperature reaches that of the environment.

Livor Mortis

the pooling of blood in dependent areas of the body after death, resulting in a purplish discoloration of the skin.

Rigor Mortis

the stiffening of the body muscles after death, occurring as a result of chemical changes in the muscles and typically beginning a few hours post-mortem.

Somatic Death

the irreversible cessation of all biological functions that sustain life, marking the end of life.

Cellular Death

the breakdown of cells and tissues, resulting from the loss of blood supply and nutrient deprivation, ultimately leading to the dissolution of cellular structures.
