What role does the pancreas play in digestion?

1. Produces bile

2. Releases digestive enzymes

3. Absorbs nutrients

4. Regulates water balance

The correct answer is: Releases digestive enzymes

The pancreas plays a crucial role in digestion primarily by releasing digestive enzymes. These enzymes, which include amylase, lipase, and proteases, are essential for breaking down carbohydrates, fats, and proteins in the food we consume. Once the pancreas secretes these enzymes into the small intestine, they function to facilitate the digestion process, allowing nutrients in food to be absorbed effectively into the bloodstream. The production of bile, which is involved in fat digestion, is actually performed by the liver, not the pancreas. While the pancreas does play a role in regulating blood sugar levels and other metabolic processes, it does not absorb nutrients directly, as that function is primarily carried out by the intestines. Additionally, regulating water balance is not a role of the pancreas; instead, it is part of the duties of the kidneys and other systems in the body. Thus, the pancreas's main contribution to digestion is through the release of these vital digestive enzymes.
