The system that contains the heart and the blood vessels and moves blood
throughout the body. This system helps
tissues get enough oxygen and nutrients, and
it helps them get rid of waste products. The lymph system, which connects with
the blood system, is often considered part of the circulatory system.
Cardiovascular diseases refer to a group of diseases
affecting the cardiovascular system (heart and blood vessels).
The narrowing or blockage of blood vessels (often due to atherosclerosis)
results in a reduced blood supply to the heart muscle. This is often
characterized by chest pain (angina) and heart attacks.
