Introduction
Under normal circumstances, bile is secreted by the liver—a vital organ. Bile is a secretion produced by hepatocytes (liver cells) and consists primarily of cholesterol, bile acids, phospholipids, bilirubin, fatty acids, and inorganic salts. The liver is one of the largest internal organs in the human body and is located in the upper right quadrant of the abdominal cavity. It is composed of numerous small structural units known as hepatic lobules.

Bile is a secretion produced by hepatocytes (liver cells), with primary components including cholesterol, bile acids, phospholipids, bilirubin, fatty acids, and inorganic salts. The liver is one of the largest internal organs in the human body, located in the upper right quadrant of the abdominal cavity. It consists of numerous small structural units known as hepatic lobules. Hepatocytes constitute the main cellular component of the hepatic lobules and play a key role in synthesizing and secreting bile; thus, bile is produced by the liver. In healthy adults, approximately 800–1000 mL of bile is synthesized and secreted daily. Bile synthesized by hepatocytes via intrahepatic bile ducts gradually converges into extrahepatic bile ducts. During fasting, bile flows through the cystic duct into the gallbladder for storage and concentration. Upon eating, the gallbladder contracts and releases stored bile into the bile ducts and subsequently into the duodenum, where it aids in the digestion and absorption of dietary fats.
If any abnormalities involving the liver are suspected, prompt medical evaluation and treatment are recommended to prevent adverse consequences.
