The role of the pancreas in digestion is multifaceted. It produces digestive enzymes such as amylase, lipase, and proteases, which are secreted into the small intestine to aid in the breakdown of carbohydrates, fats, and proteins. Additionally, the pancreas releases bicarbonate to neutralize stomach acid, creating an optimal pH for enzyme activity. It also plays a critical role in regulating blood sugar levels by secreting insulin and glucagon, ensuring that energy is available to the body according to its needs.
