What is the primary function of the pancreas?

The primary function of the pancreas entails its role in digestion, where it produces enzymes that are crucial for breaking down a variety of nutrients, including sugars, fats, and starches. The pancreas secretes amylase to break down carbohydrates into simple sugars, lipase for fat digestion, and proteases to break down proteins. Additionally, the pancreas plays a vital role in regulating blood sugar levels by producing insulin and glucagon, which help manage energy balance in the body.

The other options represent functions that are not primarily associated with the pancreas. For example, the regulation of calcium levels is primarily managed by the parathyroid glands. The production of growth hormones is a function of the pituitary gland, which is part of the endocrine system and not directly related to the pancreas. Stimulating adrenal function relates to hormones released by the adrenal glands, positioning them as separate entities with distinct roles within the body.
