Plate 10.218 Liver: Bile Canaliculi

Rabbit, Golgi method, rapid process, 162 x.

 

Bile is secreted by the hepatic cells and is composed of water, bile salts, bile pigments, cholesterol, lecithin, fat, and inorganic salts. Bile secreted into the duodenum produces an acceleration in the action of pancreatic and intestinal lipases and facilitates the absorption of fats from the intestine. Bile salts are absorbed during digestion and returned to the liver for reutilization. It is believed that the bile salts are secreted twice during the digestion of a single meal (enterohepatic circulation).

Central vein: in the center of the hepatic lobule. Receives the blood from all the sinusoids of the lobule. Also see Plates 215 and 219.

Bile canaliculi: Minute anastomosing channels formed by adjacent hepatic cells into which bile is secreted and carried to the duodenum. Also see Plate 217. ard the periphery of the lobule to enter the system of bile ducts and gallbladder. Also see Plate 218.
