MEDICAL PHYSIOLOGY

Detailed explanation-1: -Dietary lipid absorption Indeed, bile acids are of critical importance for proper lipid absorption. Bile acids are amphipathic and are present at high concentration in the intestinal lumen, allowing them to form micelles and emulsify dietary fats and cholesterol.

Detailed explanation-2: -Bile acids, the water-soluble, amphipathic end products of cholesterol metabolism, are involved in liver, biliary, and intestinal disease. Formed in the liver, bile acids are absorbed actively from the small intestine, with each molecule undergoing multiple enterohepatic circulations before being excreted.

Detailed explanation-3: -Bile salts are to a large extent (>95% per cycle) absorbed in the terminal ileum, the final section of the small intestine.
