The cardiovascular system, sometimes defined as the heart and circulatory system, is responsible for delivering blood to tissues and organs throughout the body. In addition to the heart, the cardiovascular system is comprised of the blood vessels (veins and arteries) and approximately five liters of blood. The heart, essentially a pump, circulates oxygen-carrying blood in a loop through the vast network of veins and arteries to all areas of the body and back to the lungs for re-oxygenation. In addition to oxygen, blood vessels are responsible for moving nutrients, hormones, and cellular waste.

As one of the body’s most vital systems, any injury or disease affecting cardiovascular performance should be treated with the utmost care. A heart attack is one of the most well-known, dangerous afflictions that can strike the cardiovascular system. Other conditions that can have negative cardiovascular effects include congenital heart disease and cardiomyopathy.
