Colorectal Cancer

The large intestine has different compartments. The Caecum is the first part of the large intestine, and it is 5 cm to 8 cm long. The colon is the second part of the large intestine and is divided into several parts; Those parts include ascending colon, transverse colon, descending colon, and sigmoid colon. The rectum is the last part of the large intestine, and it is 17 cm to 20 cm long and has special anatomical features called rectal folds; The fold function is to help to slow down the flow of feces as they enter the rectum. On the other hand, those folds can cause difficulties during a colonoscopy if they overlap. The terminal 3 cm to 4 cm of the rectum represents the anal canal. The opening of the anal canal is guarded by 2 sphincter muscles (internal and external).
