Májlebenyekben, often translated as "liver cells" or "hepatocytes," refers to the principal parenchymal cells of the liver. These specialized cells constitute the vast majority of the liver's mass and are responsible for its numerous metabolic, endocrine, and exocrine functions. Hepatocytes are large, polygonal cells with one or two nuclei and abundant cytoplasm filled with organelles.

Their primary roles include synthesizing bile, which aids in digestion, and producing essential proteins such as albumin, clotting factors, and enzymes. Hepatocytes also play a critical role in metabolism, processing carbohydrates, lipids, and proteins absorbed from the digestive system. They are central to detoxification, breaking down toxins, drugs, and metabolic waste products. Furthermore, they store glycogen, vitamins, and minerals.

Hepatocytes are arranged in functional units called lobules. Within these lobules, hepatocytes are organized into cords radiating from a central vein, with blood flowing from the portal triads towards the center. This intricate arrangement optimizes the exchange of substances between blood and the liver cells. Damage or dysfunction of hepatocytes can lead to a wide range of liver diseases, including hepatitis, cirrhosis, and liver failure, highlighting their vital importance to overall health.
