Colon

The large intestine is the second to last part of the final-stage digestive system digestive tract is anal-on vertebrate animals. Its function is to absorb water from digested food residue, and then to pass a useless waste material from the body. This article is mainly about the human intestine, although information about the processes that are directly applicable to most mammals.

The large intestine consists of the cecum and colon. Starting in the right iliac pelvic area, just at or below the right waist, where it joins the lower end of the small intestine. From here on until the abdomen, then across the width of the abdominal cavity, and then turned down, continue to the end point is in the anus.

The large intestine is about the length, which is about one-fifth of the entire length of the intestinal tract.
Bowel Function

The large intestine takes 32 hours to complete the remaining process of the digestive system. Food is not broken down further in the digestion stage. The large intestine only absorbs vitamins produced by bacteria that inhabit the colon. It also absorbs water and compacts dirt, and store feces in the rectum until eliminated through the anus and thus are responsible for passing along solid waste. Colon The term comes from the Latin term "Intestium Crassum"

The large intestine differs most obviously from the small intestine in the wider and in showing the longitudinal layer of muscularis has been reduced to 3 rope like structure known as taeniae coli. Bowel wall was covered with simple columnar epithelium. Instead of having the evaginations (villi), small intestine, large intestine has pelagica (intestinal glands). While both the small intestine and large intestine have goblet cells, they are abundant in the colon.

Vermiform appendix is ​​attached to its posteromedial surface of the colon. It contains masses of lymphoid tissue. This is part of the mucosa associated lymphoid tissue that gives the attachment an important role in immunity. The appendix is ​​the result of a blockage that traps infectious material in the lumen. The appendix can be removed without damage or consequences to the patient.

The large intestine extends from the ileocecal junction to the rectum and about 1.5 million long. On the surface, the band of longitudinal muscle fibers called taeniae coli, each about 5 mm wide, can be identified. There are three bands and they started at the base of the appendix and extend from the cecum to the rectum. Along side this taeniae, tags of peritoneum filled with fat, epiploic supplement called (or attachment epiploicae) found. The sacculations, haustra called, are the characteristic features of the large intestine, and distinguish it from the rest of the intestine.
