Detailed explanation-2: -The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

Detailed explanation-3: -The absorption of vitamins, minerals, and other nutrients begins in the duodenum. Food passes from the stomach into the small intestine. In the small intestine all nutrient absorption occurs. Whatever has not been absorbed by the small intestine passes into the colon.
