What Are The Functions Of Liver In Human Body – In our previous sessions on anatomy and physiology we have discussed lung anatomy, function and disease, kidney anatomy, kidney function, liver anatomy. Please check the link below
Kidney Lung Anatomy Functions, Functions and Diseases Kidney Anatomy Liver Anatomy Knowledge of the human body is very important as a healthcare professional. Today we will discuss the function of the liver Liver is an important organ of our human body It is the second largest organ in our body Therefore, every health professional must know about the liver in detail Let’s get to the point The work of life
What Are The Functions Of Liver In Human Body
Most of the functions in the human body are done by the liver The liver helps regulate blood sugar levels, and also contributes to the production, secretion, metabolism, activation, storage, and synthesis of many factors.
Exocrine Glands: Function, Examples & Types
The liver is part of the mononuclear phagocytic system It contains a large number of Kupffer cells, which are involved in immune function Kupffer cells are cells that destroy any disease-causing agents that may enter the liver through the intestine. As part of the filtration process, the liver also removes bacteria from the bloodstream
Albumin is the most common protein in blood serum It transports fatty acids and steroid hormones that help maintain proper blood pressure and prevent blood vessels from leaking.
When the kidneys produce an enzyme called renin, angiotensinogen narrows blood vessels and increases blood pressure.
Bile is a fluid that is very important for digestion Bile also helps the small intestine break down and absorb fats, cholesterol, and some vitamins. Bile contains salts, cholesterol, bilirubin, electrolytes, and water.

Carbohydrates are stored in the liver where they are broken down into glucose and released into the bloodstream to regulate glucose levels.
The liver stores large amounts of vitamins A, D, E, K, and B12, as well as iron and copper. The liver stores iron from hemoglobin in the form of ferritin, which is ready to make new red blood cells.
All blood leaving the stomach and intestines passes through the liver, which filters and removes waste products such as toxins, waste products, and other harmful substances.
Vitamin K is needed to form certain coagulants in blood clotting Bile is required for vitamin K absorption and is produced in the liver If the liver does not produce enough bile, there will be a lack of clotting
Unknown Facts About Liver
As long as 25 percent of the liver remains healthy, it can completely regenerate its function and capacity The liver is the only organ that can be completely regenerated and it grows back to its original size The new liver tissue is indistinguishable from the original tissue
Now I hope you have gained some knowledge about liver function We will discuss the topics related to Biomedical Engineering in detail in our future blogs
Pay attention. Dear Friends!!! … Please comment on a topic related to biomedicine so we can discuss it in a future blog. Weighing about 100 pounds, the liver is the second largest organ in the body; Only the skin is large and heavy The liver performs many important functions related to digestion, metabolism, immunity and nutrient storage in the body. These functions make the liver a vital organ, without which the body’s tissues would quickly die from lack of energy and nutrients Fortunately, the liver has an incredible ability to regenerate dead or damaged tissue. It can grow rapidly like a cancerous tumor to regain its normal size and function. Continue scrolling to read more below…
The liver is a triangular organ that occupies the entire abdominal cavity lower than the diaphragm Most of the liver is on the right side of the body, where it descends to the right kidney The liver is composed of very soft, pinkish-brown tissue, surrounded by a connective tissue capsule. The capsule is more covered and supported by the peritoneum of the abdominal cavity, which protects the liver and encloses it within the abdomen.
Liver Anatomy: Location, Lobes And Function
The peritoneum connects the liver at 2 sites: the coronary ligament, the left and right triangular ligaments, and the false ligament. These ligaments are not true ligaments in the anatomical sense; Rather, they are the thickened area of the peritoneal membrane that encloses the liver
The ducts that carry bile through the liver and gallbladder are known as bile ducts and form a branching structure known as the biliary tree. Bile produced by liver cells is drained into microscopic channels known as bile ducts. Innumerable bile ducts are connected to many large bile ducts found throughout the liver
These bile ducts join continuously to form the large left and right hepatic ducts, which transport bile from the left and right lobes of the liver. Those two hepatic ducts join to form the common hepatic duct, which drains all bile from the liver. The common hepatic duct eventually joins the cystic duct from the gallbladder to form the common bile duct, which transports bile to the duodenum of the small intestine. Most of the bile produced by the liver is stored in the cystic duct by peristalsis to the gallbladder until it is needed for digestion.
Blood supply to the liver is unique among all organs of the body due to the hepatic portal system Blood that has passed through the spleen, stomach, pancreas, gallbladder, and intestines passes through the capillaries of these organs and collects in the portal vein of the liver. The hepatic ducts then carry this blood to the tissues of the liver, where blood products are separated into smaller vessels and recycled before being sent to other parts of the body. Blood leaving the liver tissue collects in the hepatic veins, which return to the vena cava and the heart. The liver also has its own arteries and arterioles that supply oxygenated blood like other organs

The internal structure of the liver is composed of about 100,000 small hexagonal functional units. Each lobule consists of two central hepatic portal veins and a central vein surrounded by four hepatic arteries. These blood vessels are connected by many capillary tubes called sinusoids that extend from the portal vein and artery to meet the central vein like spokes on a wheel.
. Bile is a mixture of water, bile salts, cholesterol and bilirubin pigment Hepatocytes in the liver produce bile, which is then stored in the gallbladder via the bile ducts. When food containing fat reaches the duodenum, cells in the duodenum release the hormone cholecystokinin, which stimulates the gallbladder to release bile. Bile travels through the bile duct and into the duodenum, where it emulsifies large amounts of fat. Fat emulsions use bile to break down large fat deposits into smaller particles that have a larger surface area and are easier for the body to digest.
Bilirubin in bile is the result of the liver digesting red blood cells Kupffer cells in the liver capture and destroy old, old red blood cells and transfer their components to hepatocytes. Hepatocytes metabolize hemoglobin, the oxygen-carrying pigment of red blood cells, into components.
. The globin protein is then broken down and used as an energy source for the body The iron-containing heme group cannot be processed by the body and is converted into the pigment bilirubin and mixed with bile to be removed from the body. Bilirubin gives bile its characteristic green color Intestinal bacteria convert bilirubin to the brown pigment stercobilin, which gives stool its brown color.
Liver Disease On The Rise During Pandemic
Hepatocytes of the liver are responsible for many important metabolic functions that support the cells of the body Since all blood leaving the digestive system passes through the hepatic portal vein, the liver is responsible for converting carbohydrates, lipids, and proteins into biologically useful substances.
Our digestive system breaks down carbohydrates into the monosaccharide glucose, which cells use as a primary source of energy. Blood entering the liver through the hepatic portal vein is rich in glucose from digested food. Hepatocytes absorb most of this glucose and store it as the macromolecule glycogen, a branched polysaccharide that allows liver cells to store large amounts of glucose and rapidly release glucose into the diet. Glucose uptake and release by hepatocytes helps maintain homeostasis and protects the rest of the body from dangerous spikes and drops in blood glucose levels. (See more about glucose in the body.)
Fatty acids in the blood passing through the liver are taken up by hepatocytes and metabolized to produce energy in the form of ATP. Glycerol, another lipid component, is converted to glucose by hepatocytes in the process of gluconeogenesis. Hepatocytes can also produce lipids such as cholesterol, phospholipids, and lipoproteins that are used by other cells in the body. Most of the cholesterol produced by hepatocytes is excreted from the body as a component
