Document Summary

Functional anatomy of the liver and gallbladder: largest gland in body, under diaphragm and protected by rib cage, 4 lobes: right, left, caudate, quadrate. Functional units of the liver are composed of hexagonal lobules. Within each lobule, hepatocytes radiate a central vein. At each of the corners is a portal triad (arteriole, portal venule, and bile duct) Bile produced from the liver exits via multiple bile ducts that fuse to form the common hepatic duct. Then fuses with cystic duct to form the bile duct. Gallbladder is a thin-walled, green muscular sac. Stores and concentrates bile for eventual secretion into the duodenum via the cystic duct. Bile; alkali substance containing bile salts/pigments, cholesterol, triglycerides, phospholipids, and electrocytes. Extends across the abdomen from its tail to its head. Produces pancreatic juices (digestive enzymes and bicarbonate: secreted via the pancreatic duct to the bile duct/patopancreatic ampulla, emptying into the duodenum, the accessory pancreatic duct also empties into the duodenum.
