The major roles of the digestive system include breaking down food particles into molecules that can be absorbed into the bloodstream and delivered to the cells of the body. Which of the following structures is the location in the digestive tract where the absorption of nutrients into the bloodstream occurs?
  1. Small intestine
  2. Large intestine
  3. Esophagus
  4. Mouth
  5. Stomach
Explanation
Answer - A - The nutrients in the food you eat and digest is actually absorbed into the bloodstream in the small intestine. Before the food reaches the small intestine, most of the digestion occurs in the stomach. After food has passed through the small intestine, it moves to the larger intestine. This is where excess water is removed and the unabsorbed portions of the food are eliminated from the body.
