Explanation

The primary function of the digestive system is to:

Ingest food: Food is taken into the body through the mouth.

Break down food: Mechanical and chemical processes break down food into smaller molecules that can be absorbed.

Absorb nutrients: The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals into the bloodstream.

Eliminate waste: Undigested food and waste products are removed from the body through defecation.
