Question

In which part of the alimentary food is finally digested?

• A. Stomach
• B. Mouth Cavity
• C. Large Intestine
• D. Small Intestine

Answer 1

The correct option is D

Small Intestine

The correct option is D.

The explanation for correct option:

• The process of breaking the food particles consumed through the mouth to release soluble nutrients that can be absorbed into the bloodstream is known as digestion.
• The digestion of the food begins in the mouth of the alimentary canal and continues in the stomach.
• The final digestion occurs when the food particles are broken by the enzymes released in the small intestine, and the small intestine absorbs the resulting nutrients.

The explanation for Incorrect Options:

Option A:

• The final digestion of food does not occur in the stomach. The stomach transfers the partially digested food into the small intestine for further digestion.

Option B:

• The digestion begins in the mouth cavity but continues into the stomach and small intestine.

Option C:

• The digestive enzymes are not released in the large intestine. Thus it cannot perform the digestion of food.

Therefore, the small intestine is part of the alimentary canal responsible for final digestion.
