Digestion

Post by futulam » Tue Dec 20, 2005 3:31 am

I know that most of the digestion take place in the small intestine and that Hydrochloric acid and pepsid is the one that help digest food. If the digestion take place in the stomach and small intestine, what take place in the large intestine? does it digest more?

i know that water is absorbed in the large intestine. However NO more digestion takes place. Digestion ends in the small intestine.

Water reabsortion, some more digestion. Bacteria in colon make vitamins.

Yes, no digestion in large intestine.
And I wanted to add: Enzymes digest food. Not HCl.

HCl is used to kill invading bacteria.
Pepsin is used to digest milk proteins. :D

Not only killing. It provides acidic envionment for optimum enzyme activity.
