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:
“If the hero is not a person, the emblem
Of him, even if Xenophon, seems
To stand taller than a person stands, has
A wider brow, large and less human
Eyes and bruted ears: the man-like body
Of a primitive.”
—Wallace Stevens (1879–1955)
