Document Summary
Thin walled green muscular sac, size of a kiwi. Snuggles in a shallow fossa on the inferior surface of the liver. Stores bile that is not immediately needed for digestion. Concentrates by absorbing some of its water and ions. Bile is secreted through the cystic duct to the bile duct. ***too much cholesterol or too few bile salts allow the cholesterol to build up, forming gallstones or biliary calculi. Produces enzymes that break down all categories of foodstuffs. It is a soft, tad pole shaped gland that extends across the abdomen, it is encircled by the c shaped duodenum. Acini: clusters of secretory acinar cells that produce the enzyme rich component of pancreatic juice. Full of rough er and exhibit deeply staining zymogen granules. From the mouth, food passes into the oropharynx and then laropharynx common passageways for food, fluids and air. The mucosa contains a friction resistant stratified squamous epithelium well supplied with mucus producing glands.
