Question

which part of the human gastrointestinal tract produces digestive enzymes?
1 esophagus
2 appendix
3 small intestine
4 large intestine

Explanation:

To solve this, we analyze each option:

• The esophagus transports food, no enzyme production.
• The appendix has a role in immunity/gut flora, not enzyme production.
• The small intestine (specifically the brush border and with help from pancreatic enzymes) produces and uses digestive enzymes for nutrient breakdown.
• The large intestine absorbs water/electrolytes, no significant enzyme production for digestion.

So the small intestine is the correct part.

Answer:

1. small intestine
