The term "rectal" refers to anything related to the rectum, which is the final section of the large intestine in the human body. It plays a crucial role in the digestive system by storing feces until they are expelled from the body. Rectal examinations and procedures are often performed by healthcare professionals to assess the health of the rectum and surrounding areas. These may include checking for abnormalities, such as hemorrhoids or polyps, and are important for diagnosing various medical conditions.
