자주 묻는 질문

What are the main functions of the liver?
The liver performs over 500 known functions. Key roles include metabolizing carbohydrates, fats, and proteins; detoxifying drugs, alcohol, and metabolic waste products; producing bile for fat digestion; synthesizing plasma proteins including albumin and clotting factors; and storing glycogen, vitamins (A, D, B12), and iron. It is the primary organ of metabolism.
Where is the liver located?
The liver is located in the upper right quadrant of the abdomen, beneath the diaphragm and above the stomach. It is the largest solid organ in the body, weighing approximately 1,400–1,600 grams in adults. It is covered by a fibrous capsule (Glisson's capsule) and is divided into right and left lobes separated by the falciform ligament.
What is liver cirrhosis?
Cirrhosis is a late-stage liver disease characterized by replacement of normal liver tissue with fibrotic scar tissue, disrupting normal liver architecture and function. Common causes include chronic alcohol use, hepatitis B or C infection, and non-alcoholic fatty liver disease. Complications include portal hypertension, ascites, hepatic encephalopathy, and increased risk of hepatocellular carcinoma.
