Human feces (or faeces in British English; ) are the feces (solid waste products) of the human digestive system, including bacteria. They vary significantly in appearance (i.e. size, color, texture), according to the state of the digestive system, diet and general health. Normally human feces are semisolid, with a mucus coating. Small pieces of harder, less moist feces can sometimes be seen impacted on the distal (leading) end. This is a normal occurrence when a prior bowel movement is incomplete, and feces are returned from the rectum to the intestine, where water is absorbed.
