Detailed Solution

Defecation is the process by which faecal matter is removed through the anus.

It is the process by which waste products are eliminated from the body and occurs when the muscles in the rectum wall contract and push the faeces out of the body through the anus.

The rectum is a muscular tube that serves as a temporary storage area for faeces and signals the brain to begin the defecation process when it becomes full.

Defecation is a complex process that requires the coordinated contraction of muscles in the abdominal wall, diaphragm, and pelvic floor, as well as the relaxation of the internal anal sphincter, a muscle ring that controls the release of faeces from the rectum.

Proper faecal elimination is essential for good health because it prevents waste material buildup in the colon and lowers the risk of constipation and other digestive problems.
