Скачать или смотреть Gastro Intestinal System: Defacation Pathway

Defecation is the term for the act of expelling feces from the digestive tract via the anus. This complex function requires coordination between the gastrointestinal, nervous, and musculoskeletal systems.

The process begins with mass movement from the colon to the rectum, initiating the defecation reflex, which involves rectal contraction and internal and external anal sphincter relaxation. Defecation is involuntary from the colon to the internal anal sphincter, where smooth muscles push feces out.

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder.

The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus.

The liver, pancreas, and gallbladder are the solid organs of the digestive system.
