What is the primary role of the pancreas in human physiology?

The primary role of the pancreas in human physiology is the secretion of digestive enzymes. The pancreas is a vital organ in the digestive system, functioning as both an endocrine and exocrine gland. As an exocrine gland, it produces digestive enzymes such as amylase, lipase, and proteases, which are released into the small intestine to aid in the breakdown of carbohydrates, fats, and proteins. This enzymatic action is crucial for nutrient absorption and overall digestive health.

In contrast, bile production is primarily a function of the liver, not the pancreas. Regulation of body temperature is handled by the hypothalamus and various physiological mechanisms unrelated to pancreatic function. Although the pancreas does play a role in glucose regulation through insulin secretion (an endocrine function), its primary responsibility within the digestive context is indeed the secretion of digestive enzymes, which is essential for proper digestion and metabolism.
