담즙, or bile, is a digestive fluid produced by the liver. It plays a crucial role in breaking down fats in the small intestine, aiding in the digestion and absorption of nutrients. Bile is stored in the gallbladder until it is needed for digestion. The composition of 담즙 includes bile salts, cholesterol, bilirubin, and electrolytes. When food enters the duodenum, the first part of the small intestine, the gallbladder releases bile to help emulsify fats, making them easier for enzymes to digest. This process is essential for proper nutrient absorption and overall digestive health.
