What is "anus"?
The anus is a muscular opening located at the end of the digestive tract in the human body. It serves as the exit point for solid waste materials, allowing for their elimination during the process of defecation. The anus is lined with sensitive skin and contains internal and external sphincter muscles that help regulate the passage of stool.
