Large Intestine (colon)
The colon is the main reservoir for feces (mainly in rectum) before defecation. It is also where the liquid stool becomes solid, by losing its water, and electrolytes. The colon also actively secretes bicarbonate and potassium, which explains why severe diarrhea can cause metabolic acidosis as well as hypokalemia. The colon also houses symbiotic bacteria that produce vitamin by-products and are essential to the human health and homeostasis.

Famous quotes containing the words large and/or intestine:
“It is surprising on stepping ashore anywhere into this unbroken wilderness to see so often, at least within a few rods of the river, the marks of an axe, made by lumberers who have either camped here or driven logs past in previous springs. You will see perchance where, going on the same errand that you do, they have cut large chips from a tall white pine stump for their fire.”
—Henry David Thoreau (1817–1862)
“Which came first the intestine or the tapeworm?”
—William Burroughs (b. 1914)
