The rectum and anal canal form the last portion of the gastrointestinal tract. The rectum serves as a reservoir for fecal contents, and the anal canal regulates continence and defecation via synchronization of events regulated by complex interactions between sympathetic and parasympathetic nerves, striated and smooth muscle, and environmental factors.

The transverse colon crosses the midline of the abdomen, from right to left at the cranial border of the mesentery. The descending colon continues caudally to the rectum and anus. It has a sigmoid flexure before it enters the pelvic cavity. Upon entering the colon, the food residue first travels up the ascending colon on the right side of the abdomen. At the inferior surface of the liver, the colon bends to form the right colic flexure (hepatic flexure) and becomes the transverse colon.

The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the caecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts. The colon and rectum are held in the abdomen by folds of tissue called mesenteries. Cecum The cecum is a pouchlike passage that connects the colon to the ileum (the last part of the small intestine).

It is the last part of the colon before the rectum. It acts as a site for water absorption from the faeces, as a site for flatus to be stored before being expelled, and as a site of peristalsis. It frames the small intestines on three sides and has the following subdivisions: cecum, appendix, colon, rectum, and anal canal. The saclike cecum is the first part of the large intestine.
