Hepatic Anatomy

Right hepatic vein divides the right lobe into anterior and posterior segments. Weighing about 3 pounds the liver is reddish brown in color and feels rubbery to the touch.

Surgical Anatomy Of The Liver Abdominal Key

The liver is a large meaty organ that sits on the right side of the belly.

Hepatic anatomy. About 7085 of the liver volume is occupied by parenchymal hepatocytes. Parenchymal cells and nonparenchymal cells. The liver has multiple functions.

This plane runs from the inferior vena cava to the gallbladder fossa. This is the dominant blood supply to the liver parenchyma and allows the liver to perform its gut related functions such as detoxification. The common hepatic duct transports the bile made by the liver cells to the gallbladder and duodenum the first part of the small intestine via the common bile duct.

Confusion surrounds the nomenclature of liver anatomy. Hepatocytes heparliver cytecell are responsible for making many of the proteins protein synthesis. Nonparenchymal cells constitute 40 of the total number of liver cells but only 65 of its volume.

Functions of the liver the liver regulates most chemical levels in the blood and excretes a product called bile. It is pinkish brown in color with a soft consistency and is highly vascular and easily friable. The liver is a roughly triangular organ that extends across the entire abdominal cavity just inferior to the diaphragm.

Anatomy of the liver gross anatomy. The liver is an irregular wedge shaped organ that lies below the diaphragm in the right upper quadrant of the abdominal cavity and is in close approximation with the diaphragm stomach and the gallbladder. Middle hepatic vein divides the liver into right and left lobes or right and left hemiliver.

The liver has the general shape of a prism or wedge with its base to the right and its apex to the left see the image below. It makes many of the chemicals required by the body to function normally it breaks down and detoxifies substances in the body and it also acts as a storage unit. It is derived from the coeliac trunk.

The liver is made of very soft pinkish brown tissues encapsulated by a connective tissue capsule. Most of the livers mass is located on the right side of the body where it descends inferiorly toward the right kidney. It is largely covered by the costal cartilages.

Hepatic portal vein 75 supplies the liver with partially deoxygenated blood carrying nutrients absorbed from the small intestine. Hepatic artery proper 25 supplies the non parenchymal structures of the liver with arterial blood. Histology the study of microscopic anatomy shows two major types of liver cell.
