Information about Enterogastrone
Enterogastrone is any substance in the lower gastrointestinal tract which opposes the caudal (or "forward, analward") motion of the contents of chyme when exposed to lipids.
Examples include:
Mucus is a slippery secretion of the lining of the mucous membranes in the body.
