Anaus is a misspelling of "anus." The anus is the end of the large intestine, specifically the last 3-4 centimeters of it, which opens to the outside of the body to allow for the elimination of feces (poop).
Here's a breakdown:
- The anus is the external opening of the rectum.
- The rectum is the final section of the large intestine.
- Its main function is to expel waste from the body.
- The tissue lining the inside of the large intestine transforms into normal skin at the anus.
Therefore, the anus is the exit point for solid waste, marking the boundary between the digestive system and the external environment.
