5ft in length, 3 inches in diameter
Mostly absorb water (approx. 1400 ml per day)
Compacts the material into solid waste (feces; 100 ml/day)
Muscular sphincter (Ileocolic valve), allows food from small intestine to large intestine
Spasmodic contraction- helps move the fecal material father along the colon
Rectum- the final segment of the colon is the rectum which functions for the storage of feces and its elimination(defecation)
Two muscular sphincters: internal anal sphincter is under involuntary and is always in a state of contraction and external sphincter is voluntary and is made up of skeletal muscle
