What is the Site of Most Chemical Digestion

Question

What is the site of most chemical digestion?
A) Stomach
B) Mouth
C) Cecum
D) Duodenum

Accepted Answer

The duodenum is the site of most chemical digestion. This is where enzymes from the pancreas, liver, and gallbladder mix with chyme from the stomach to break down carbohydrates, fats, and proteins. The stomach and mouth also contribute to chemical digestion, but not to the same extent as the duodenum. The cecum is primarily involved in the absorption of water and electrolytes.
