The primary role of the pancreas is to regulate blood sugar levels and aid in digestion. It functions as both an endocrine and exocrine gland. In its endocrine capacity, the pancreas secretes insulin and glucagon, hormones that control glucose metabolism and maintain blood sugar stability. The exocrine function involves producing digestive enzymes that are released into the small intestine to assist in breaking down carbohydrates, proteins, and fats. This dual functionality is crucial for metabolic balance and overall health, playing a vital role in digestion and energy regulation in the body.
