The primary function of the pancreas in digestion is the production and secretion of digestive enzymes and hormones. It produces enzymes such as lipase, amylase, and proteases, which aid in the breakdown of fats, carbohydrates, and proteins, respectively, in the small intestine. Additionally, the pancreas secretes hormones like insulin and glucagon that regulate blood sugar levels. This dual role in both enzyme production and hormonal regulation makes the pancreas essential for effective digestion and metabolic homeostasis in the body.
