The hepatic lobules are composed of hepatic blood sinusoids, perisinusoidal spaces, central veins, hepatic plates and bile ducts. The hepatic lobule is the basic structure of the liver and needs to be examined under a microscope by stained sections to be seen. The lobules are cystic and columnar in shape, about 1mm wide and 2mm high, and the human liver consists of about 500,000 to 1,000,000 lobules. There is a central vein, hepatic sinusoids, perisinusoidal space and bile ducts in the middle of each hepatic lobule, centered on the central vein, which together form a complex three-dimensional configuration of the hepatic lobule. Liver lobules have the functions of metabolism, immunity, synthesis, secretion, excretion, etc. If the patient drinks too much alcohol and eats too much greasy and stimulating food, the central steatosis of liver lobules may occur. Therefore, in life, we should pay attention to eat more green vegetables, fruits and fiber-rich foods, do not drink and smoke, etc., to protect the liver lobules from damage. It should be noted that patients should pay attention to their own physical condition, if they suffer from loss of appetite, pain in the liver area, etc., they should go to the hospital for examination in a timely manner, so as to avoid inflammation of the liver lobules.
