What Are 3 Functions Of The Liver
The liver, the largest gland in the body, is a concentrated organ with many metabolic and excretory functions. The liver secretes digestive juices into the gallbladder. Metabolizes proteins, carbohydrates, and fats. Stores glycogen, vitamins and other substances. Synthesizes clotting factors to remove waste and toxins from the blood. Regulates blood volume and destroys old red blood cells.
The Mammalian Liver: Structure (5.2.2)
Liver tissue consists of cells lined with bile and blood vessels. Liver cells make up about 60 percent of the tissue and perform more metabolic functions than any other group 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 absorption of foreign particles and cellular debris.
The liver secretes about 800-1000 milliliters (1 quart) of bile every day, which contains bile that is needed for fat absorption. It is also a means of removing certain metabolic waste products, drugs and toxins. A duct system from the liver drains the gallbladder into the common bile duct, which empties into the colon and is stored in the gallbladder. The presence of fat in the duodenum increases the flow of bile from the gallbladder and into the colon. Old red blood cells are destroyed in the liver, spleen, and bone marrow. Hemoglobin, a pigment formed during the breakdown of bilirubin, is released into the gallbladder, producing a characteristic greenish-yellow color, and is excreted through the intestines.
Liver cells synthesize several enzymes. As blood flows through the liver, portal vein, and hepatic artery, cells and enzymes are filtered. Food that enters the liver from the intestine is converted into forms that can be used by the body’s cells or stored for the future. Fatty acids are converted to fatty acids, then to carbohydrates or ketone bodies, and transported through the blood to the tissues where they are metabolized. Sugar is converted into glycogen, which is stored in the liver until it is needed for energy production. It is then converted to glucose and released into the blood. The liver produces and releases serum proteins, including albumin and several clotting factors. The liver also metabolizes nitrogenous waste products, detoxifying them and preparing them for elimination in the urine or feces.
A common symptom of liver failure is jaundice, a yellowing of the eyes and skin due to excess bilirubin in the blood. Jaundice is caused by abnormal levels of red blood cell destruction (hemorrhagic jaundice), bilirubin release by liver cells (hepatomegaly), or biliary obstruction (obstructive jaundice). Liver cell failure can result from hepatitis, cirrhosis, tumors, stroke, or poisoning. Symptoms include weakness, low blood pressure, easy bruising and bleeding, tremors, and fluid accumulation in the abdomen. Blood tests may reveal abnormalities of bilirubin, cholesterol, serum proteins, urea, ammonia, and various enzymes. Liver problems can be diagnosed with certainty.
Foods Good For Your Liver
The liver is also susceptible to various disorders and diseases. A suppurative abscess is caused by acute appendicitis. Bile duct problems can occur with gallstones or after surgery. In the tropics, the parasite that causes amoebic dysentery also causes hepatitis. Liver infections are caused by a variety of parasites found in different parts of the world. Liver cancer occurs as a secondary tumor that develops elsewhere in the body. Glycogen storage diseases, a group of genetic disorders that cause excess glycogen in the liver and insufficient glucose in the blood. Some medications can cause jaundice and liver damage. The liver is an abdominal organ. Food is part of the digestive system. Sometimes people use the adjective liver or liver when referring to the liver.
Liver disease makes a person sick because of all the important things the liver does. People with liver cancer usually die if they cannot receive a liver transplant. The recently deceased man’s liver was surgically transplanted. This type of operation is usually technically difficult but can save lives.
The liver can’t remove toxins and waste, so these bad things stay in the blood longer. One thing that builds up is a substance called bilirubin. When red blood cells die, the hemoglobin inside them is released into the blood. Hemoglobin is converted to bilirubin (a yellow substance that turns the gallbladder yellow). The liver removes bilirubin from the blood and stores it in the gallbladder. Bile goes into the intestines and comes out with the waste from your body. If the liver is damaged, it cannot remove bilirubin, so bilirubin remains in the body. This makes a person’s body look yellow and is called jaundice. Therefore, yellow eyes and yellow skin are symptoms of liver disease.
Hepatitis is inflammation (swelling or enlargement) of liver cells. This may be caused by a virus. This can be caused by toxins or poisons. The most common toxin that causes hepatitis is alcohol. There may also be genetic or autoimmune causes when the body’s immune system attacks itself.
Alagille Syndrome: Symptoms, Causes & Treatment
Cirrhosis results from the repeated death of liver cells. When cells die, scar tissue forms. This scar tissue destroys the structure of the liver. It also keeps the liver from working. But it also increases the pressure in the arteries leading to the liver. This high pressure causes esophageal changes. The most common cause of cirrhosis worldwide is hepatitis B infection.
Certain diseases can cause bad things to happen to the liver. Atherosclerosis causes excess iron to build up in the liver. Wilson’s disease causes extra copper to build up in the liver. Both of these diseases damage cells and cause liver disease, which kills people.
You can get liver cancer. It could be metastatic cancer elsewhere in your body. The liver is a common metabolic site because it removes bad things from the blood. Therefore, it removes cancer cells from the blood and grows in the liver. Liver cysts can also occur. If it develops in the liver, it can lead to liver cancer. Most hepatocellular carcinoma results from cirrhosis.
Some liver diseases can be easily treated with medication. Hemophilia is treated depending on the severity of the disease by withdrawing (removing) the patient’s blood in an amount equal to that of a normal blood donor (~470 mL).
Foods For A Healthy Liver
Some hepatitis viruses can be prevented before they develop. Both types of viral hepatitis can be prevented by immunization. A total of five lifetime shots of hepatitis A and hepatitis B can be prevented.
Liver is a good source of protein, as is muscle meat. It is also an excellent source of certain micronutrients. The taste is strong for some people, so it’s a little bitter. If you eat too much it can be toxic.

Unlike more specific organs, the liver has multiple functions spread throughout the body. In some ways, he’s a comfortable person who keeps everything in the background.
