The intestinal structure and function
The human intestine consists of two essential parts: small intestine and large intestine. The small intestine connects directly to the stomach. It is two to three meters long and lies in many loops in the abdomen. The small intestine has the task of further digesting the food pre-digested by saliva and gastric juices and ingesting the usable nutrients into the body via the intestinal mucosa. The undigested residue of the food enters the intestine.
The colon (colon) has a length of about 1 to 1.5 meters. The last section of the large intestine is called the rectum or rectum. This is about 15-20 centimeters long and is closed to the outside by the so-called continence organ (closure system), a combination of muscles, including the sphincter. The disorder of this important function is often an indication of an onset disease, but also a tumor growth in this region. The function of colostrum and rectum is primarily to thicken the undigested intestinal contents by draining the water and collect them for emptying. The inner wall of the intestine is lined with a mucous membrane on which the stool moves from the intestinal musculature to the anus. The chair is finally emptied of the chair. The intestine also contributes significantly to regulating fluid balance in the body.
