The pancreas plays a crucial role in the human body by serving two main functions: the production of digestive enzymes and the regulation of blood sugar levels. As an exocrine gland, it secretes enzymes into the small intestine to help with the digestion of proteins, fats, and carbohydrates. As an endocrine gland, it releases hormones like insulin and glucagon into the bloodstream to maintain normal blood glucose levels. The proper functioning of the pancreas is vital for overall metabolic health.
