What in duodenum triggers the release of bile by the gallbladder?

The presence of lipids (fat) in the duodenum trigger bile to enter the duodenum via the bile duct. Bile is produced in the pancreas, then stored in the gall bladder until it is need in the duodenum for breaking down fat into fat droplets. Bile contains bile slats that help in the process of emulsification of fats without which fats cannot be digested. emulsification of fats also increases the surface area of the fat molecules, speeding digestion.


What helps the digestion systeme absorb calcium?

absorption of calcium is influenced by conditions within the lumen of the small intestine . The acid secretion from the stomach converts the calcium to a salt, which is absorbed primarily in the duodenum


What is the excretory organ for bile?

AnswerThe gall bladder.Bile is secreted by the liver, but it is stored in the gallbladder. During digestion, bile is discharged into the duodenum (small intestine) and aids in the emulsification, digestion, and absorption fat.
