It is the organ that absorbs the water in the food residue, and the food residue itself forms feces and is discharged to some extent. It is an important part of the human digestive system. It is the lower part of the digestive tract. The length of the adult large intestine is about 1.5m. It starts from the ileum and can be divided into five parts: cecum, appendix, colon, rectum and anal canal. The whole process is shaped like a box around the jejunum and ileum. The large intestine is different from the small intestine in appearance. Generally, the diameter of the large intestine is thicker and the wall of the small intestine is thinner. The cecum and colon also have three characteristic structures: 1. On the surface of the intestine, there is a colon belt along the intestinal heald, which is formed by the thickening of the longitudinal muscles of the intestinal wall; 2. The transverse sulcus on the intestinal wall becomes a cystic colon bag; 3 Fat process is called intestinal fat drop.

Second: the large intestine is located in the abdomen, its upper mouth is connected with the small intestine at the appendix door, and its lower end is connected with the anus. The upper part of the large intestine is called "ileum", including the upper part of ileum and colon in modern anatomy; the lower part is called "wide intestine", including sigmoid colon and rectum. The large intestine is also a kind of official organ. It has the physiological function of transferring dross and main body fluid.

The third is the structure of the rectum. The mucosa on the inner surface of the ampulla of the rectum forms 2-3 transverse folds of the rectum in the shape of large intestine (5 pieces). One of them is located in the right anterior wall, which is large and constant, about 7cm away from the anus, which is equivalent to the level of peritoneal refolding. The transverse fold is often used as a marker when the relationship between rectal tumor and peritoneal cavity is determined by sigmoidoscopy. These transverse folds support the feces.
