Anal Canal

The anal canal is the last stop for poop before it sees the light of day.
Definition of Anal Canal
The anal canal is situated between the rectum and anus. When someone decides it's time (or the body decides for them), poop leaves the rectum, passes through the anal canal, and exits the body through the anus.
Diagram of the Anal Canal
This diagram shows where the anal canal is in relation to the entire large intestine.
What is the Pectinate Line?
Imagine the anal canal as a circular room with pink walls. Now imagine that this circular room has short curtains all the way around -- pink curtains that hang in columns and reach about halfway down the wall.
