An accessory digestion gland, the liver performs a wide range of functions, such as synthesis of bile , glycogen storage and clotting factor production. In this article, we shall look at the anatomy of the liver — its position, structure, and neurovascular supply. When discussing the anatomical position of the liver, it is useful to consider its external surfaces, associated ligaments, and the anatomical spaces recesses that surround it. Fig 1 — The liver lies in the right hypochondrium of the abdomen, and is surrounded by numerous organs. The external surfaces of the liver are described by their location and adjacent structures.

What does the liver do?

The liver performs many essential functions related to digestion, metabolism, immunity, and the storage of nutrients within the body. These functions make the liver a vital organ without which the tissues of the body would quickly die from lack of energy and nutrients. Fortunately, the liver has an incredible capacity for regeneration of dead or damaged tissues; it is capable of growing as quickly as a cancerous tumor to restore its normal size and function. The liver is a roughly triangular organ that extends across the entire abdominal cavity just inferior to the diaphragm. The liver is made of very soft, pinkish-brown tissues encapsulated by a connective tissue capsule. This capsule is further covered and reinforced by the peritoneum of the abdominal cavity, which protects the liver and holds it in place within the abdomen.

The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines. These lobules are connected to small ducts tubes that connect with larger ducts to form the common hepatic duct. 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. The liver regulates most chemical levels in the blood and excretes a product called bile.

Liver , the largest gland in the body, a spongy mass of wedge-shaped lobes that has many metabolic and secretory functions. The liver secretes bile , a digestive fluid; metabolizes proteins, carbohydrates, and fats; stores glycogen , vitamins, and other substances; synthesizes blood-clotting factors; removes wastes and toxic matter from the blood ; regulates blood volume; and destroys old red blood cells. Liver tissue consists of a mass of cells tunneled through with bile ducts and blood vessels. Hepatic cells make up about 60 percent of the tissue and perform more metabolic functions than any other group of cells in the body. Each day the liver secretes about to 1, ml about 1 quart of bile, which contains bile salts needed for the digestion of fats in the diet. Bile is also the medium for excretion of certain metabolic waste products, drugs, and toxic substances.
