Detailed Solution

Defaecation is the process of eliminating undigested and unabsorbed food material from the body through the anus. It is the final stage of the digestion process, during which undigested food material, along with dead cells and bacteria from the digestive tract, is expelled from the body in the form of feces.

When food enters the digestive system, it is broken down into smaller molecules by mechanical and chemical processes. These smaller molecules are then absorbed by the body and used for various functions such as energy production and growth. The remaining undigested and unabsorbed material passes through the large intestine where water is absorbed, and the waste material is formed into feces.
