Which pair below correctly matches the cell type with their secretion?

• A. Duct cells: proteases.
• B. Duct cells: bicarbonate.
• C. Acinar cells: water.
• D. Acinar cells: bile salts

Answer: (B)

Verified step by step guidance

1. Understand the role of duct cells and acinar cells in the body. Duct cells are typically involved in transporting and modifying secretions, while acinar cells are responsible for producing and secreting digestive enzymes and other substances.
2. Identify the primary secretion of duct cells. In the pancreas, duct cells secrete bicarbonate ions (HCO₃⁻) to neutralize stomach acid in the small intestine.
3. Recognize the function of acinar cells. In the pancreas, acinar cells secrete digestive enzymes such as proteases, lipases, and amylases, which aid in the digestion of proteins, fats, and carbohydrates, respectively.
4. Evaluate the options given in the problem. Match the cell type with its correct secretion based on their known physiological roles.
5. Conclude that the correct match is 'Duct cells: bicarbonate' and 'Acinar cells: proteases', as these align with the known functions of these cell types in the digestive system.
