What is the role of the pancreas in digestion?

• A. To store bile for fat digestion
• B. To produce digestive enzymes and hormones like insulin
• C. To absorb nutrients from food
• D. To break down alcohol in the bloodstream

Answer: (B)

The pancreas plays a crucial role in digestion primarily through its functions in producing digestive enzymes and hormones. It secretes a range of digestive enzymes, including amylase, lipase, and proteases, which aid in the breakdown of carbohydrates, fats, and proteins, respectively, as the food passes into the small intestine. This enzymatic digestion is essential for nutrient absorption. Additionally, the pancreas produces hormones such as insulin and glucagon, which are crucial for regulating blood sugar levels. Insulin helps cells take up glucose from the bloodstream, while glucagon raises blood sugar levels when they are too low. This dual role of the pancreas as both an exocrine gland (producing digestive enzymes) and an endocrine gland (producing hormones) is vital for maintaining homeostasis and assisting in digestion. In contrast, the other choices do not accurately describe the primary functions of the pancreas. For instance, storing bile is the function of the gallbladder, while nutrient absorption occurs in the small intestine. The liver primarily breaks down alcohol in the bloodstream, not the pancreas.
