Anus
The anus is an opening at the end of the digestive tract through which feces, or wastes, are expelled from the body. It is the terminal part of the rectum, which connects the distal part of the large intestine to the outside of the body. It is important for the body to expel waste, as it helps to prevent infection, constipation, and other digestive disorders. The anus is also used in sexual activity, including anal sex and pegging, in which a dildo or other sex toy is inserted into the anal opening.
