Cardiovascular refers to the circulating system. It is responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the bod. The cardiovascular system is powered by the body’s hardest-working organ — the heart, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 liters of blood throughout the body every minute.
