Question

Quizplus · Accepted Answer

The duodenum is the first part of the small intestine and is responsible for receiving the partially digested food from the stomach. The wall of the duodenum secretes a variety of enzymes including disaccharidases (such as lactase, sucrase, and maltase) which help break down complex carbohydrates into simple sugars that can be absorbed by the body. The pancreas also secretes disaccharidases, but this occurs downstream in the small intestine. The gallbladder is not involved in the secretion of enzymes for digestion, and the stomach primarily secretes hydrochloric acid and pepsinogen for protein digestion.
