<unk>  are varicosities or swelling and inflammation of veins in the rectum and anus. The rectum is the last part of the large intestine leading to the anus. The anus is the opening at the end of the digestive tract where bowel contents leave the body.
External<unk>  are located under the skin around the anus. Internal<unk>  develop in the lower rectum. Internal<unk>  may protrude, or prolapse, through the anus. Most prolapsed<unk>  shrink back inside the rectum on their own. Severely prolapsed<unk>  may protrude permanently and require treatment.
