Detailed explanation-1: -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-2: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Detailed explanation-3: -Your circulatory system, which consists of your heart, blood and blood vessels, are responsible for transporting nutrients to the cells of your body. Specifically, nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins.
Detailed explanation-4: -The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair. Unused materials are discarded as faeces (poo).
