The blood vessels along the small intestine walls absorb these substances and blood cells are then able to transport these to the body's cells and tissues.he relationship between the circulatory and digestive system is mainly basic-without one, the other cannot function properly. The blood absorbs (takes in) nutrients in the small intestine. The blood help transport these nutrients so that it can be used by the cell tissues in the body.
