Document Summary

Necessary for life, located in urq of the abdo, second largest organ. Greatest ability to regenerate of all the tissues in the body but requires the basic structure to be intact. Large fxnl reserve meaning that you can lose a lot of it and you will have good fxn. Disorders are relatively common, diverse sxs due to variety of fxns. Hepatic artery brings fresh blood from the heart. Branches of the hepatic artery, portal vein and bile duct all drain into the central vein. Bile ducts carry secretions to the major bile system. They are small capillary like structures that are surrounded by hepatocytes and covered in epithelial layer that is 1 cell thick. They are more permeable than the capillary bc of the space fenestrations - between the endothelial cells (no tight jxn) Very close contact with the blood allowing for free flow between the sinusoid and hepatocyte.
