What does desiccation refer to in the context of post-mortem changes?

• A. Cooling of the body
• B. Drying of body tissues
• C. Pooling of blood
• D. Stiffening of muscles

Answer: (B)

Desiccation refers specifically to the drying of body tissues after death. This process occurs due to a lack of moisture as the body no longer has metabolism to maintain fluid balance. In the post-mortem context, desiccation can significantly affect the appearance and consistency of various tissues, particularly when the body is exposed to air or a dry environment. As moisture evaporates, tissues can shrink and become brittle, which can have implications for the examination and identification of remains. The other choices represent different post-mortem phenomena. Cooling of the body, also known as algor mortis, refers to the drop in body temperature following death. Pooling of blood, known as livor mortis, describes the settling of blood under gravity in the lowermost parts of the body, leading to discoloration of the skin. Stiffening of muscles, or rigor mortis, is the process where muscles become rigid after death due to biochemical changes. Each of these processes serves a distinct role in the post-mortem changes of the body, but desiccation specifically highlights the drying aspect of body tissues.
