Arteries carry oxygene (blood) to organs and organs use the blood given by arteries to function and preform certain tasks needed for survival the blood used by the organs go to the major veins in the body which are recirculated by the heart and are transfered to the lungs which add oxygene to the unoxigenated blood through the tiny sacks in the lungs (avioli)
