A. Small intestine
B. Large intestine
C. Stomach
D. Liver

Check Answer

The correct answer is option A) Small Intestine.

The digestion of food is completed in the small intestine. While digestion begins in the mouth and continues in the stomach, it is in the small intestine where most of the nutrients from the food are broken down and absorbed into the bloodstream.

The small intestine is a long, narrow tube located between the stomach and the large intestine. It receives digestive enzymes and bicarbonate from the pancreas and bile from the liver, which help to break down the food and neutralize the acidic chyme (partially digested food) from the stomach. The walls of the small intestine are lined with tiny finger-like projections called villi, which increase the surface area for the absorption of nutrients into the bloodstream.
