Question

which structures of the digestive system, aside from the small intestine, release substances that help break down food in the small intestine?
stomach and liver
liver and large intestine
pancreas and liver
large intestine and pancreas

Explanation:

The liver produces bile which is stored in the gallbladder and released into the small intestine to emulsify fats. The pancreas produces pancreatic juice containing enzymes like amylase, lipase, and protease which are released into the small intestine to further break down carbohydrates, fats, and proteins respectively. The stomach's role is mainly in the initial digestion (like protein digestion with pepsin) and its contents (chyme) move to the small intestine. The large intestine's main functions are water absorption and feces formation, not releasing substances for digestion in the small intestine.

Answer:

pancreas and liver
