Rectum
The rectum is the final section of the large intestine in the human digestive system. It serves as a temporary storage site for feces before they are expelled from the body. Located between the colon and the anus, the rectum plays a crucial role in the excretion process by holding waste until it is convenient for the body to eliminate it.
Muscles in the rectum help control the passage of feces, ensuring that elimination occurs at a suitable time. This process is supported by the internal and external anal sphincters, which work together to maintain continence and allow for voluntary control over bowel movements.
The rectum also contributes to various reflexes in the body, helping manage the urge to defecate and facilitating smooth, efficient elimination. Understanding the function and health of the rectum is important for maintaining good digestive health and recognizing potential issues, such as constipation or hemorrhoids.
