A hepatocyte is a type of cell found in the liver, which is the largest internal organ in the human body. These cells play a crucial role in various metabolic processes, including the production of bile, detoxification of harmful substances, and storage of nutrients like glucose and vitamins. Hepatocytes make up about 70-80% of the liver's mass and are essential for maintaining overall health. Hepatocytes are organized into structures called lobules, which are the functional units of the liver. Each lobule contains a central vein surrounded by plates of hepatocytes, allowing for efficient blood flow and nutrient exchange. The health of hepatocytes is vital, as damage to these cells can lead to liver diseases such as hepatitis or cirrhosis.
