Question

question 21
which accessory organ of the digestive system does not produce any enzymes or digestive secretions?
a pancreas
b gallbladder
c liver
d salivary glands
e teeth

Explanation:

• Pancreas: Produces pancreatic enzymes (e.g., amylase, lipase, protease) and bicarbonate.
• Gallbladder: Stores and concentrates bile (produced by the liver). It does not produce enzymes or digestive secretions on its own.
• Liver: Produces bile (which aids in fat digestion).
• Salivary glands: Produce saliva containing salivary amylase.
• Teeth: Mechanical digestion (chewing), no enzymatic or secretory production related to digestion in the sense of chemical secretion. But the question asks about "accessory organ" - teeth are part of the oral cavity (not an accessory organ in the traditional sense of digestive - system accessory organs like pancreas, liver, gallbladder). The gallbladder is an accessory organ that only stores bile (no production of its own enzymes/secretions).

Answer:

B. gallbladder
