What Are The Digestive Functions Of The Liver – The liver is an important organ in the human body located in the upper right of the abdomen. It plays a central role in various essential functions, including metabolizing nutrients, detoxifying the blood, producing bile for digestion, storing glycogen and synthesizing proteins. It is a crucial organ for overall health and well-being.

Carbohydrate metabolism: The liver helps regulate blood sugar levels by storing excess glucose as glycogen and releasing it when needed.

What Are The Digestive Functions Of The Liver

The liver produces bile, a greenish liquid that aids digestion by emulsifying fats and aiding absorption in the small intestine.

The liver helps regulate blood volume and composition by removing and storing excess blood, as well as producing blood clotting factors.

It plays a role in the immune system by filtering and removing bacteria and foreign particles from the blood.

Overall, the liver is a central organ for maintaining homeostasis in the body, regulating and supporting a number of vital physiological processes. It is essential for overall health and well-being.

The 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 coagulation factors; removes waste and toxic substances from the blood; regulates blood volume; and destroys old red blood cells.

What Bile Is, Where It’s Made, And What It Does

Liver tissue consists of a mass of cells tunnelled through with bile ducts and blood vessels. Liver cells make up about 60 percent of the tissue and perform more metabolic functions than any other group of cells in the body. A second group of cells, called Kupffer cells, line the smallest channels of the liver’s vascular system and play a role in blood formation, antibody production and the ingestion of foreign particles and cellular waste.

Every day, the liver secretes about 800 to 1,000 ml (about 1 liter) of bile, which contains bile salts necessary for the digestion of dietary fats. Bile is also the medium for the excretion of certain metabolic waste products, drugs and toxic substances. From the liver, a duct system carries bile to the common bile duct, which opens into the duodenum of the small intestine and connects to the gallbladder, where it is concentrated and stored. The presence of fat in the duodenum stimulates the flow of bile out of the gallbladder and into the small intestine. Aging (worn out) red blood cells are destroyed in the liver, spleen and bone marrow. A pigment, bilirubin, formed in the process of hemoglobin breakdown, is released in the bile, creating its characteristic greenish-orange color, and is excreted from the body through the intestine.

The liver cells synthesize a number of enzymes. As blood flows through the liver, both from the portal vein and from the hepatic artery, the cells and enzymes are filtered. Nutrients that enter the liver from the gut are modified into forms that can be used by the body’s cells or stored for future use. Fat is converted into fatty acids and then into carbohydrates or ketone bodies and transported with the blood to the tissues, where they are further metabolised. Sugar is converted into glycogen, which remains stored in the liver until needed for energy production; it is then converted to glucose and released into the bloodstream. The liver produces blood serum proteins, including albumin and several clotting factors, and supplies them to the blood. The liver also metabolizes nitrogenous waste products and detoxifies toxic substances, preparing them for elimination in the urine or feces.

Liver cells, or hepatocytes, have direct access to the liver’s blood supply through small capillaries called sinusoids. Hepatocytes perform many metabolic functions, including the production of bile. Kupffer cells line the vascular system of the liver; they play a role in blood formation and destruction of cellular waste.

Functions Of Gallbladder

A common sign of reduced liver function is jaundice, a yellowing of the eyes and skin as a result of too much bilirubin in the blood. Jaundice can be caused by an abnormally high level of destruction of red blood cells (hemolytic jaundice), defective uptake or transport of bilirubin by the liver cells (hepatocellular jaundice), or a blockage in the bile duct system (obstructive jaundice). Failure of liver cells to function can be caused by hepatitis, cirrhosis, tumours, vascular obstruction or poisoning. Symptoms may include weakness, low blood pressure, easy bruising and bleeding, tremors and fluid retention in the abdomen. Blood tests can reveal abnormal levels of bilirubin, cholesterol, serum proteins, urea, ammonia and various enzymes. A specific diagnosis of a liver problem can be established by performing a needle biopsy.

The liver is susceptible to a number of other ailments and diseases. Abscesses can be caused by acute appendicitis; those that occur in the bile ducts may be due to gallstones or may follow surgery. The parasite that causes amoebic dysentery in the tropics can also produce liver abscesses. Various other parasites prevalent in different parts of the world also infect the liver. Liver cancer is common, and mostly occurs as secondary tumors originating elsewhere in the body. Glycogen storage diseases, a group of inherited disorders, generate an accumulation of glycogen in the liver and an insufficient supply of glucose in the blood. Certain medicines can damage the liver and produce jaundice. The liver is a vital organ that performs a wide range of important functions in the body. Some of the main functions of the liver include:

Overall, the liver is a crucial organ that performs a wide range of vital functions essential to maintaining good health.
