Cardiovascular exercise is any exercise that gets the heart rate up and increases blood circulation. Cardiovascular exercise utilizes large muscle groups. Aerobic exercise requires to use large muscle groups rhythmically and continuously. These muscle movement over a sustained period of time keep the heart rate to at least 50% of its maximum level.
Answer: My answer to this is physiology because it is the movement of blood through the vessels from the arteries to the capillaries and into the veins.
