Liver cells, also known as hepatocytes, are the main functional cells of the liver. They play a crucial role in various metabolic processes, including the production of bile, which helps in digestion, and the regulation of blood sugar levels. Hepatocytes also detoxify harmful substances, such as drugs and alcohol, making them essential for maintaining overall health. In addition to their metabolic functions, liver cells are involved in the synthesis of proteins, including albumin, which helps maintain blood volume and pressure. Hepatocytes can regenerate, allowing the liver to recover from damage or disease, highlighting their importance in the body's ability to heal.
