    How do nutrients, absorbed by the small intestine, travel to the individual cells of the body?
    The nutrients move from the small intestine directly to the live and then move through the lymphatic system to the body cells.
    The nurtients are absorbed from the small intestine into the blood and move through the circulatory system to the body cells
    The small intestine forces the nutrients into the kidneys where the nutrients are then dissolved in fluids used by the body cells
    The body cells send nerve impulses indicating a lack of nutrients to the small intestine and the small intestine sends the nutrients back to the cells.
