The portion of the large intestine located between the cecum and rectum is termed the colon. It consists of four parts; ascending, transverse, descending, and sigmoid. The main functions of the colon include fluid and electrolyte reabsorption. In addition, the microflora generates energy through a process called fermentation. The colon has a segmented appearance; its segments, which are caused by sacculation, are called haustra. The ascending colon, descending colon and rectum are located in the retroperitoneum (outside the peritoneal cavity). The transverse and sigmoid colon are attached to the posterior abdominal wall by the mesocolon.

After the distal descending colon has curved medially it enters the pelvis, where it gains a mesentery and is then called the sigmoid colon.It measures approximately 15 cm in length. The colon is divided into four parts: the ascending, transverse, descending and sigmoid. The ascending and transverse colon meet at the right hepatic flexure (near the liver). The transverse and descending colon meet at the left splenic flexure (near the spleen). The large intestine has three bands of longitudinal muscle fibers called taeniae coli. Anatomy The large pouch at the beginning of the large intestine, located in the lower right-hand side of the abdomen.

The colon itself is made up of the caecum, the ascending colon, the hepatic flexure, the transverse colon, the splenic flexure, the descending colon and the sigmoid colon (Figure 1). It is about 1.5 m long, the transverse colon being the longest and most mobile part (Meschan, 1975), and has a average diameter of about 6.5 cm.

The large intestine (also known as the large bowel) is a 1.5 meter muscular tube that extends from the cecum to the rectum.It has three outer longitudinal muscular layers called taenia coli, which are about 30 cm shorter than the length of the large bowel causing characteristic sacculations interrupted by incomplete rings called haustra 1.The large bowel is divided into the following parts: 2017-01-22 Colon Anatomy: Description: Parts of the colon; drawing shows the ascending colon, cecum, transverse colon, descending colon, sigmoid colon, and rectum. The colon includes the ascending colon, cecum, transverse colon, descending colon, sigmoid colon, and rectum. Topics/Categories: Anatomy -- Digestive/Gastrointestinal System: Redundant colon . One variation on the normal anatomy of the colon occurs when extra loops form, resulting in a longer than normal organ.

The ileum (last part of the small intestine) connects to the cecum (first part of the colon) in the lower right abdomen.

The colon has a segmented appearance; its segments, which are caused by sacculation, are called haustra. The ascending colon, descending colon and rectum are located in the retroperitoneum (outside the peritoneal cavity). The transverse and sigmoid colon are attached to the posterior abdominal wall by the mesocolon.
