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.

Liver: Anatomy and Functions

The liver is the largest solid organ and the largest gland in the human body. It carries out over essential tasks. Classed as part of the digestive system, the roles of the liver include detoxification, protein synthesis, and the production of chemicals that help digest food.

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.

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 peritoneum connects the liver in 4 locations: the coronary ligament, the left and right triangular ligaments, and the falciform ligament.

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.

The liver is an organ only found in vertebrates which detoxifies various metabolites , synthesizes proteins and produces biochemicals necessary for digestion and growth. Its other roles in metabolism include the regulation of glycogen storage , decomposition of red blood cells , and the production of hormones. The liver is an accessory digestive organ that produces bile , an alkaline fluid containing cholesterol and bile acids , which helps the breakdown of fat. The gallbladder , a small pouch that sits just under the liver, stores bile produced by the liver which is afterwards moved to the small intestine to complete digestion.
