Introduction
The human liver is located in the abdominal cavity, with the majority situated in the right upper quadrant and a smaller portion in the left upper quadrant. It is the largest solid glandular organ in the human body, typically weighing approximately 1200–1600 g—about 1/50 of an adult’s body weight. The liver is slightly heavier in males than in females. In fetuses and newborns, the liver is relatively larger, accounting for up to 1/20 of body weight.
The liver—one of the most vital organs in the human body—performs numerous critical functions, including detoxification (removal of oxidative stress), nutrient storage, and synthesis and secretion of essential proteins. It is the largest internal organ and a key metabolic organ, typically weighing approximately 1.5 kg (about three Chinese “jin”).
Location of the Liver
The human liver resides within the abdominal cavity, occupying predominantly the right upper quadrant, with a smaller portion extending into the left upper quadrant. As the largest solid glandular organ in the body, it typically weighs between 1,200–1,600 g—approximately 1/50 of an adult’s total body weight. On average, males have slightly heavier livers than females. In fetuses and newborns, the liver is relatively larger, accounting for about 1/20 of body weight.
A healthy liver has a reddish-brown appearance and a soft, friable texture. Its shape resembles an irregular wedge: the right lobe is broad and blunt, whereas the left lobe is narrower. Typical dimensions are approximately 25 cm in length (left-to-right diameter), 15 cm in width (anterior-to-posterior diameter), and 6 cm in thickness (superior-to-inferior diameter). The superior surface is convex and conforms to the diaphragm; the inferior surface is relatively flat and lies adjacent to the stomach, duodenum, gallbladder, and transverse colon.
The liver’s superior border aligns with the diaphragm, reaching approximately the level of the fifth right rib. Due to its anatomical attachments, the liver exhibits some mobility, shifting slightly upward or downward with changes in posture and respiration. Its inferior border normally does not extend beyond the costal margin; under normal conditions, it cannot be palpated below the ribs. Occasionally, the liver edge may be felt just beneath the xiphoid process, but rarely extends more than 3 cm below this point. In children, however, the liver edge is often palpable below the costal margin.
Poor liver health can significantly impair daily life—even subtle hepatic dysfunction (before overt disease develops) may adversely affect everyday functioning. Individuals who neglect liver health—such as those relentlessly pursuing career advancement or academic excellence, or the growing number of self-proclaimed “liver warriors” (“Gan Di”)—may experience transient satisfaction from their achievements, but such gains come at a real cost to hepatic integrity. Prioritizing healthy lifestyle habits—including regular sleep patterns—is essential for preserving liver function and overall well-being.
