Where is Bile Secreted?

Bile is usually secreted in the liver, mainly by hepatocytes, and is continuously secreted and stored in the gallbladder. Bile is mainly composed of bile salts, cholesterol, bile pigments, lecithin, calcium, sodium, potassium, and other components, but does not contain digestive enzymes. After hepatocytes secrete bile, it usually enters the capillaries through the hepatic lobules, and then is transported by the capillary bile ducts. After mixing with the bile ducts, it usually reaches the gallbladder for storage. Bile can usually be directly excreted from the liver and gallbladder into the duodenum in large quantities, promoting the digestion of fats and the absorption of fat-soluble vitamins, while also neutralizing gastric acid. The daily secretion of bile in adults can reach between 800ml and 1000ml, and the secretion of bile can usually increase after eating high-protein foods. Bile is an indispensable digestive juice in the human digestive system. If secretion is insufficient, it may lead to indigestion and bring adverse effects to the body. Therefore, in daily life, it is necessary to maintain a good diet and avoid overeating to reduce the burden on the gastrointestinal tract. If the body experiences discomfort, it is recommended to visit a formal hospital for treatment.
