The left and right lobes of the liver are marked by the sickle ligament, which is in a sagittal position, so the liver is divided into two lobes, left and right, by this. The right border of the coronary ligament is divided into anterior and posterior layers, and the liver has four edges: anterior, posterior, left and right, and two surfaces: the diaphragmatic surface and the dirty surface, through which more blood vessels and the largest superior and inferior vena cava in the human body pass again. Most of the liver is located mainly in the right quadrant and the supra-abdominal region, with a small part in the left quadrant. The front of the liver is mostly covered by the ribs, with a small part exposed under the saber, which can easily lead to liver rupture when a violent blow occurs with a rib fracture. The anatomical location of the liver is connected to the heart of the lung, and when there is an abscess in the liver, it can adhere to the diaphragm and invade the right lobe of the lung. The central part of the liver with malignant tumors can also invade the surrounding organs, such as the upper part of the duodenum, the kidney and adrenal glands in the posterior part, etc.
