Which organ produces pancreatic juice and hormones like glucagon and insulin?

• A. Stomach
• B. Pancreas
• C. Liver
• D. Gallbladder

Answer: (B)

The pancreas handles both digestion and glucose regulation. Its exocrine tissue makes pancreatic juice rich in enzymes (amylase, lipase, proteases) and bicarbonate, which flows into the small intestine to help break down carbohydrates, fats, and proteins. At the same time, endocrine tissue in the pancreas—the islets of Langerhans—produces hormones insulin and glucagon that regulate blood sugar. Insulin promotes glucose uptake by tissues, lowering blood glucose, while glucagon stimulates glucose release from the liver, raising blood glucose when needed. Other organs listed have different roles: the stomach digests with acid and enzymes, the liver performs metabolic tasks and makes bile, and the gallbladder stores bile. So the organ that produces both pancreatic juice and hormones like glucagon and insulin is the pancreas.
