3. Liver Largest visceral organ divided into two lobes
1/11/2019
Liver
Largest visceral organ
divided into two lobes
each lobe contains 100,000 hepatocytes
Hepatocyte functions
clean blood
store iron and other heavy metals
forms bile - sent to gallbladder
drug inactivation

5. Digestive function of Hepatocytes
1/11/2019
Digestive function of Hepatocytes
Carbohydrate metabolism
Lipid metabolism
amino acid metabolism
vitamin storage
fat soluble vitamins
A,E,D,K, B12
Acquire nutrients directly from small intestine via hepatic portal vein

6. Gallbladder Releases bile through common bile duct Bile function
1/11/2019
Gallbladder
Releases bile through common bile duct
guarded at the duodenum by sphincter of Oddi
Bile function
Break open lipids to lipase can digest
Bile salts are recycled by ileum
Gallstone - bile salt precipitates - block common bile duct

7. Hormones Gastrin Secretin Released by stomach
1/11/2019
Hormones
Gastrin
Released by stomach
causes release of gastric juices and increases motility
released at sight, smell, or ingestion of food
Secretin
stimulates the release of buffers and water released into duodenum

8. Hormones Cholecystokinen (CCK) secreted when chyme hits duodenum
1/11/2019
Hormones
Cholecystokinen (CCK)
secreted when chyme hits duodenum
Releases sphincter of Oddi
Stimulates the production of pancreatic juices
inhibits gastric activity

9. Nutrient absorption Carbohydrates (monosaccharides)
1/11/2019
Nutrient absorption
Carbohydrates (monosaccharides)
through microvilli to blood stream
facilitated diffusion
Proteins (amino acids)
Lipids (triglycerides)
through microvilli to lymph
diffusion - nonpolar substances
