摘要: The bile, essential for digestion and absorption of nutrients, is secreted by the liver continuously, stored in gallbladder during fasting, discharged into duodenum intermittently after each meal. bile salts, which are an important component promote efficient nutrients from intestine. has a unique mechanism to sequester almost all salts fasting release them arrival food. Food stimulates endogenous cholecystokinin circulation endocrine cells lining mucosa duodenum, jejunum, upper ileum. Cholecystokinin (CCK) acts on its receptors located smooth muscle initiates contraction emptying concentrated gallbladder; it simultaneously relaxes sphincter Oddi allow passage duodenum.
