The hepatic region is located in the right upper abdomen and is anatomically the right quaternary rib region, mostly covered by the rib arch. In a normal person, the liver is on the right midclavicular line, roughly between the fifth and seventh intercostal spaces; on the right midaxillary line, roughly between the sixth and eighth intercostal spaces; and on the posterior scapular line, between the eighth and tenth intercostal spaces. The liver moves up and down in response to breathing, and can usually rise and fall about 2 to 3 centimeters. The liver is the largest digestive gland in the body, and the vast majority of it is in the right upper abdomen, i.e., the right quaternary region, with a small portion reaching the left quaternary region. The liver is irregularly wedge-shaped and can be divided into upper and lower surfaces with left and right lobes. If the liver is touched at the lower edge of the costal arch during liver palpation, it is pathologically enlarged and requires prompt medical attention. If there is any discomfort in the liver, it is recommended to consult a doctor in time.
