Ingested food is chewed, swallowed, and passes v the esophagus into the stomach where it is damaged down into a liquid called chyme. Chyme overcome from the stomach into the duodenum. Over there it mixes through bile and pancreatic juices the further malfunction nutrients. Finger-like projections called villi heat the interior wall surface of the little intestine and also absorb most of the nutrients. The continuing to be chyme and also water happen to the large intestine, i beg your pardon completes absorption and also eliminates waste.

Large Intestine

The huge intestine compacts liquid waste right into solid waste.

Villi the line the walls of the tiny intestine absorb nutrients into capillaries the the circulatory system and also lacteals the the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels referred to as lacteals. Fat acids took in from broken-down chyme pass into the lacteals. Other absorbed nutrients go into the bloodstream v the capillary beds and also are taken directly to the liver, via the hepatic vein, because that processing.

2. The large Intestine Completes Absorption and also Compacts Waste

Chyme passes from the tiny intestine v the ileocecal valve and also into the cecum that the huge intestine. Any kind of remaining nutrients and some water are took in as peristaltic waves move the chyme into the ascending and also transverse colons. This dehydration, combined with peristaltic waves, help compact the chyme. The solid waste created is dubbed feces. It proceeds to move through the descending and sigmoid colons. The big intestine temporarily stores the feces before elimination.

3. Defecation Eliminates Waste from the Body

The body expels waste assets from digestion with the rectum and also anus. This process, called defecation, entails contraction the rectal muscles, relaxation of the internal anal sphincter, and an initial contraction of the bones muscle the the exterior anal sphincter. The defecation reflex is mainly involuntary, under the command that the autonomic nervous system. However the somatic concerned system additionally plays a role to control the time of elimination.
