Description

Whats is Rectum? The rectum is the final part of the digestive tract located between the sigmoid colon and the anus. Here's a brief overview of the anatomy and functions of the rectum: Anatomy: 1. Location: The rectum is situated in the pelvis, running in a curved shape from the sigmoid colon to the anus. 2. Length: It measures approximately 12 to 15 centimeters in length in adults. 3. Structure: The rectal wall consists of layers of smooth muscle, blood vessels, nerves, and mucous membrane lining. Functions: • Storage of Feces: The primary function of the rectum is to store feces, which are the waste products of digestion, until they are ready to be eliminated from the body during a bowel movement. • Sensory Function: The rectum contains specialized nerve endings that can detect the presence of stool, signaling the brain when it's time to have a bowel movement. • Coordination of Defecation: The rectum plays a crucial role in coordinating the process of defecation. When the rectum is adequately distended with stool, nerve signals are sent to the brain, triggering the urge to defecate. The rectal muscles contract, and the anal sphincter muscles relax to allow the elimination of stool. • Absorption of Water: The rectum absorbs water from the fecal matter as it is held and stored, contributing to the formation of solid stool. It's important to maintain a healthy diet, including sufficient fiber and hydration, to support proper rectal function and bowel movements. Regular bowel movements and maintaining good colorectal health are essential for overall digestive well-being. Common Diseases of Rectum are: • Rectal Prolapse • Solitary Rectal Ulcer Syndrome (SRUS) • Cancer of Rectum
