The 췌장, or pancreas, is a vital organ located behind the stomach. It plays a crucial role in digestion by producing enzymes that help break down food in the small intestine. Additionally, the pancreas produces hormones, including insulin, which regulates blood sugar levels. In humans, the pancreas is about 6 to 8 inches long and has both endocrine and exocrine functions. The endocrine part releases hormones into the bloodstream, while the exocrine part secretes digestive enzymes. Proper functioning of the 췌장 is essential for maintaining overall health and metabolic balance.
