Physiological Functions of the Liver

Within the context of metabolism, the liver is the site of a multitude of biochemical reactions essential to the human organism; included are synthesis, degradation, interconversion, storage, and biotransformation. A working knowledge of the relationship between structure and function and of hepatic processes under normal conditions is essential for understanding the derangements observed in clinical diseases affecting the liver. Our overview of hepatic physiology highlights some of these facets of normal hepatic anatomy and function of special relevance to the physician confronting liver dysfunction and its varied clinical consequences.

Liver: Anatomy and Functions

The liver is the largest organ in the body. It is located below the diaphragm in the right upper quadrant of the abdominal cavity. An adult's liver weighs approximately 3 pounds and extends approximately from the right 5th rib to the lower border of the rib cage. The liver is separated into a right and left lobe, separated by the falciform ligament. The right lobe is much larger than the left lobe. The working cells of the liver are known as hepatocytes.

The liver normally weighs between 1. It is the second-largest organ in the body, and is located on the right side of the abdomen. The liver plays a major role in metabolism and has a number of functions in the body, including glycogen storage, plasma protein synthesis, and drug detoxification. It also produces bile, which is important for digestion. The liver is supplied by two main blood vessels on its right lobe: the hepatic artery and the portal vein. The portal vein brings venous blood from the spleen, pancreas, and small intestine so that the liver can process the nutrients and byproducts of food digestion.

Liver plays an essential role in metabolism and has an important role in preserving and regulating the levels of lipid, glucose in the body as well as energy metabolism. Among the important functions performed by the liver is maintaining of blood glucose levels under different conditions through group of processes included; glycolysis, glycogenesis, glycogenolysis, gluconeogenesis. The absorbed free fatty acids and those derived from the adipose tissue reach the liver and are utilized for energy, membrane synthesis, or stored as triglyceride. In addition, the liver has a crucial role in keeping homeostasis of body level of cholesterol. Regarding protein metabolism, urea cycle occurs in the liver through the action of urea cycle enzymes to produce urea in order to get rid of the toxic ammonia.
