The rectum is the final segment of the large intestine located just above the anus. Its primary function is to store feces until they are ready to be eliminated from the body. The rectum is responsible for the voluntary control of defecation, allowing the individual to determine the appropriate time and place for bowel movements. It also contains sensory receptors that provide feedback on the consistency and volume of stool, aiding in the regulation of bowel movements. The rectum plays a vital role in the elimination of waste materials from the body through the process of defecation.
