What Does Liver Do In Human Body – The liver is a large organ that sits in the upper right abdomen, below the right lung. It is one of the most “intelligent” organs of the body, which performs many different functions at the same time. The liver makes proteins, removes waste products from the body, produces cholesterol, stores and releases glucose for energy, and metabolizes many drugs used in medicine. It also produces bile that flows through the bile ducts into the intestines, where it helps digest food. This remarkable organ also has the ability to regenerate itself if injured or partially removed. The liver receives blood from two different sources – the heart and the intestine. All this blood flows through the liver and returns to the heart. No wonder the ancient Chinese considered the liver, not the heart, to be the center of the body.

Many types of chronic injury to the liver can lead to scar tissue. This scar distorts the normal structure and regrowth of liver cells. Blood flow from the intestine through the liver is blocked and interferes with the liver’s ability to process drugs or produce proteins.

Cirrhosis takes years to develop. During this time, there are usually no symptoms, but fatigue, weakness, and loss of appetite may occur and worsen over time. When cirrhosis is fully developed, there may be several signs:

Detailed Guide On Liver Cirrhosis

A physician can always suspect cirrhosis from a patient’s medical history and physical examination. In addition, some blood tests and scans or ultrasound (sonography) can provide helpful information. However, to make an accurate diagnosis, a liver biopsy (tissue sample) is required. This is done by anesthetizing the skin of the right-lower chest and inserting a thin needle into the liver. A core or sample of tissue is removed and examined under a microscope.

When cirrhosis is diagnosed, the patient and physician begin an action plan designed to preserve the remaining liver cells and correct the above-mentioned problems. By following this plan, many patients can live long, productive lives.

Perhaps 90 percent of cirrhosis is caused by excessive alcohol consumption, fatty liver disease, or hepatitis viruses. Of course, alcoholism can be avoided. Alcohol consumption should always be limited to no more than 1 or 2 drinks per day. And type B hepatitis now has an effective vaccine against it. Vaccination against hepatitis B virus is safe and inexpensive. It should be taken especially by certain high-risk groups: all health care professionals, people traveling to third world countries, homosexuals, intravenous drug users and prostitutes.

Liver transplantation has now reached the stage where it is considered the standard treatment for selected patients.

Fatty Liver Disease: What It Is And What To Do About It

Cirrhosis of the liver is a common disorder that has many causes. With early diagnosis, much can be done to prevent serious complications. Different treatments are available depending on the cause of liver injury and its complications. Ongoing medical research promises major advances in the treatment of cirrhosis in the future.

The liver, the largest gland in the body, is 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 waste and toxins from the blood; Regulates blood volume; and destroys old red blood cells.

Body Torso Showing The Liver And Part Of The Digestive System

Liver tissue consists of a mass of cells tunneled by bile ducts and blood vessels. Hepatic cells make up 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 tiniest channels of the liver’s vascular system and play a role in blood formation, antibody production, and the uptake of foreign particles and cellular debris.

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

Liver cells synthesize many enzymes. As blood flows through the liver, from the portal vein and from the hepatic artery, cells and enzymes are filtered. Nutrients entering the liver from the intestine are converted into usable forms by body cells or stored for future use. Fats are converted into fatty acids and then into carbohydrates or ketone bodies and transported through the blood to the tissues where they are further metabolized. Sugars are converted into glycogen, which is stored in the liver until needed for energy production; It is then converted back into glucose and released into the bloodstream. The liver makes blood serum proteins, including albumin and several clotting factors, and supplies them to the blood. The liver also metabolizes nitrogenous waste products and detoxifies toxins, preparing them for elimination in the urine or feces.

A common sign of impaired liver function is jaundice, a yellowing of the eyes and skin that results from excess bilirubin in the blood. Jaundice can be caused by an abnormally high level of red blood cell destruction (hemolytic jaundice), uptake or transport of bilirubin by hepatic cells (hepatocellular jaundice), or a blockage in the biliary system (obstructive jaundice). Hepatic cell dysfunction can be caused by hepatitis, cirrhosis, tumors, vascular obstruction, or poisoning. Symptoms may include weakness, low blood pressure, easy bruising and bleeding, tremors, and fluid accumulation in the abdomen. Blood tests 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.

Liver is subject to many other disorders and diseases. Acute appendicitis can cause abscesses; Occurrences in the bile ducts can be caused by gallstones or follow surgery. The parasite that causes amoebic diarrhea in the tropics also produces liver abscesses. Many other parasites that are prevalent in different parts of the world also infect the liver. Liver cancer is common, mostly occurring as secondary tumors originating elsewhere in the body. Glycogen-storage diseases, a group of hereditary disorders, produce an accumulation of glycogen in the liver and an insufficient supply of glucose in the blood. Some drugs can damage the liver, producing jaundice. Anatomy of the Liver. The liver is located in the upper abdomen near the stomach, intestines, gallbladder, and pancreas. The liver has four lobes. Two lobes are located in front and two smaller lobes (not shown) are located behind the liver. Intrahepatic bile ducts are a network of small tubes that carry bile

Each year in the United States, about 25,000 men and 11,000 women get liver cancer, and about 19,000 men and 9,000 women die from the disease. The percentage of Americans who get liver cancer has increased over several decades, but is now decreasing. Liver cancer is more common in other parts of the world than in the United States.

In its early stages, liver cancer may not have visible or palpable symptoms. However, when the cancer is large, people may notice one or more of these common symptoms. It is important to remember that these symptoms can also be caused by other health conditions. If you have any of these symptoms, consult your doctor.
