What is the primary function of the pancreas in relation to digestion?

1. Secretion of bile

2. Absorption of nutrients

3. Production of insulin and enzymes

4. Storage of glycogen

The correct answer is: Production of insulin and enzymes

The primary function of the pancreas in relation to digestion is the production of insulin and enzymes. The pancreas plays a crucial role in the digestive process by secreting digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine. These enzymes include amylase for carbohydrate digestion, proteases for protein digestion, and lipases for fat digestion. Additionally, the pancreas produces insulin, a hormone that helps regulate blood sugar levels, which is vital for maintaining energy balance in the body. The presence of these enzymes is essential for effective digestion and nutrient absorption that occurs in the gastrointestinal tract. Although bile is involved in digestion, it is produced by the liver and stored in the gallbladder, so that option is not relevant to the pancreas. The absorption of nutrients primarily occurs in the intestines rather than the pancreas itself. While the pancreas does store glycogen as a component of glucose metabolism, its primary role in digestion is as an enzyme producer and hormone regulator.
