Anatomy of the large intestine. The large intestine consists of the cecum colon rectum and anal canal. The large intestine consists of the cecum appendix ascending colon transverse colon descending colon rectum and anal canal. The invaginations are called the intestinal glands or colonic crypts.

The large intestine is responsible for processing indigestible food material chyme after most nutrients are absorbed in the small intestine. The cecum the colon the rectum and the anus. The large intestine is about 5 feet 15 m in length and 25 inches 6 7 cm in diameter in the living body but becomes much larger postmortem as the smooth muscle tissue of the intestinal wall relaxes.

Gross and microscopic anatomy of the large intestine the large intestine is that part of the digestive tube between the terminal ileum and anus. The wall of the large intestine is lined with simple columnar epithelium with invaginations. The large intestine or large bowel is the last part of the digestive system in vertebrate animals.

Depending on the species ingesta from the small intestine enters the large intestine through either the ileocecal or ileocolic valve. Although shorter than the small intestine in length the large intestine is considerably thicker in diameter thus giving it its name. Its function is to absorb water from the remaining indigestible food matter and then to pass the useless waste material from the body.

The large intestine is named for its relatively large diameter not its length. To be more precise it starts from the right iliac region of the pelvis. The colon crypts are shaped like microscopic thick walled test tubes with a central hole down the length of the tube the crypt lumen.

The large intestine is subdivided into four main regions.
