What is the primary function of the pancreas?

The primary function of the pancreas is to regulate blood sugar and aid in digestion. It does this through two key roles: exocrine and endocrine functions.

In its exocrine capacity, the pancreas produces digestive enzymes that help break down carbohydrates, fats, and proteins in the small intestine, which is essential for proper digestion and nutrient absorption. Meanwhile, in its endocrine role, the pancreas monitors and regulates blood glucose levels through the secretion of hormones like insulin and glucagon. Insulin lowers blood sugar levels by facilitating the uptake of glucose into the body's cells, while glucagon raises blood sugar levels by signaling the liver to release stored glucose.

This dual functionality underscores the pancreas's critical role in metabolic processes and maintaining overall homeostasis in the body regarding energy balance and digestion. Other options do not encompass the complete functions of the pancreas or are inaccurately attributed to it.
