Humans expel feces with a frequency varying from a few times daily to a few times weekly. [1] Waves of muscular contraction (known as peristalsis) in the walls of the colon move fecal matter through the digestive tract towards the rectum. Undigested food may also be expelled within the feces, in a process called egestion.
This may lead to constipation symptoms such as incomplete evacuation of stool, [1] irregular bowel movements, [1] hard stools [1] and the need for excessive straining. [ 1 ] [ 3 ] Compared to the more natural squatting position, western-style toilets may lead to health issues [ 1 ] such as inflamed hemorrhoids.
Human feces photographed in a toilet, shortly after defecation.. Human feces (American English) or faeces (British English), commonly and in medical literature more often called stool, [1] are the solid or semisolid remains of food that could not be digested or absorbed in the small intestine of humans, but has been further broken down by bacteria in the large intestine.
Children with loose stools and diarrhea (colonic hypermotility): This group of children has an overactive colon. Rapid transit of stool results in frequent episodes of diarrhea . This means that even when an enema cleans the colon rather easily, stool keeps on passing fairly quickly from the cecum to the descending colon and the anus.
Only the proximal stoma is functioning. Most often, double-barrel colostomy is a temporary colostomy with two openings into the colon (distal and proximal). The elimination occurs through the proximal stoma. Colostomy surgery that is planned usually has a higher rate of long-term success than surgery performed in an emergency situation.

A cloaca (/ k l oʊ ˈ eɪ k ə / ⓘ kloh-AY-kə), pl.: cloacae (/ k l oʊ ˈ eɪ s i / kloh-AY-see or / k l oʊ ˈ eɪ k i / kloh-AY-kee), or vent, is the rear orifice that serves as the only opening for the digestive (), reproductive, and urinary tracts (if present) of many vertebrate animals.
The opening through which the catheter is introduced into the pouch is called the stoma. It is a small, flat, button-hole opening on the abdomen. Most patients cover the stoma site with a small pad or bandage to absorb the mucus that accumulates at the opening. [17] [Note 1] This mucus formation is natural, and makes insertion of the catheter ...
The water and stool may take some time to fully evacuate, especially with patients with obstructed defecation. People with reduced muscular strength of the anal sphincter may encounter problems with later leakage of the water mixed with stool, which may bring similar, socially devastating problems as seen with fecal incontinence.
