Explanation:
the circulatory system is responsible for the transportation of nutrients and gases like oxygen for the body and metabollic waste products away from the body . the heart and the lungs play an important role in circulating and purification of blood throughout the body.
the heart is the key organ for blood circulation as it provides an effective way of circulation. the main difference is that the blood flow two routes --
