Overview
The large intestine is the last part of the gastrointestinal (GI) tract, the long, tube-like pathway that food travels through your digestive system. It follows from the small intestine and ends at the anal canal, where food waste leaves your body.
Function
When the large intestine receives food from the small intestine, the food has been liquified by the digestive process and most of the nutrients have been absorbed. The colon’s job is to dehydrate what’s left of the food and form it into stool. It does this by slowly absorbing water and electrolytes as its muscle system moves the waste along.
Anatomy
The large intestine is in your lower abdominal cavity from your waist down. It surrounds the small intestine in a sort of a square question mark shape, with the tail of the question mark ending at the anal canal.
