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:
“In most nineteenth-century cities, both large and small, more than 50 percent—and often up to 75 percent—of the residents in any given year were no longer there ten years later. People born in the twentieth century are much more likely to live near their birthplace than were people born in the nineteenth century.”
—Stephanie Coontz (20th century)
“Which came first the intestine or the tapeworm?”
—William Burroughs (b. 1914)
