májszövetet

Májszövetet refers to liver tissue. The liver is a vital organ located in the upper right quadrant of the abdomen, beneath the diaphragm and on top of the stomach, right kidney, and intestines. It plays a crucial role in numerous bodily functions, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion.

Histologically, májszövetet is characterized by hepatocytes, which are the primary functional cells of the liver. These cells are arranged in lobules, with a central vein in each lobule. Blood from the digestive organs, rich in nutrients, flows through sinusoids within the lobules, where hepatocytes can process it. The liver also contains other cell types, such as Kupffer cells, which are macrophages that help clear debris and pathogens, and stellate cells, involved in vitamin A storage and fibrosis.

Diseases affecting májszövetet can range from viral hepatitis and fatty liver disease to cirrhosis and liver cancer. Damage to liver tissue can impair its ability to perform its essential functions, leading to a variety of health problems. Medical professionals often examine májszövetet through biopsies or imaging techniques to diagnose and monitor liver conditions. The regenerative capacity of the liver is notable, meaning it can often repair itself to some extent when damaged, though severe or chronic injury can lead to irreversible scarring and loss of function.
