How is feces eliminated from the body




















Common Problems with Elimination Diarrhea and constipation are some of the most common health concerns that affect digestion.

Emesis Emesis, or vomiting, is elimination of food by forceful expulsion through the mouth. Provided by : Boundless. October 17, Provided by : Wikibooks. Located at : en. Provided by : Wikipedia.

The salivary glands, liver , gallbladder , and pancreas are major accessory organs that have a role in digestion. These organs secrete fluids into the digestive tract. Digestion and absorption occur in the digestive tract. After the nutrients are absorbed, they are available to all cells in the body and are utilized by the body cells in metabolism. Any remaining nutrients and some water are absorbed as peristaltic waves move the chyme into the ascending and transverse colons.

This dehydration, combined with peristaltic waves, helps compact the chyme. The solid waste formed is called feces. It continues to move through the descending and sigmoid colons. The large intestine temporarily stores the feces prior to elimination. The body expels waste products from digestion through the rectum and anus.

This process, called defecation, involves contraction of rectal muscles, relaxation of the internal anal sphincter, and an initial contraction of the skeletal muscle of the external anal sphincter. The defecation reflex is mostly involuntary, under the command of the autonomic nervous system. But the somatic nervous system also plays a role to control the timing of elimination. A bowel movement is the last stop in the movement of food through your digestive tract.

Your stool passes out of your body through the rectum and anus. Another name for stool is feces. It is made of what is left after your digestive system stomach, small intestine, and colon absorbs nutrients and fluids from what you eat and drink. Sometimes a bowel movement isn't normal.
