The cardiovascular system (your heart and blood vessels) supplies your body's organs with oxygen and nutrients so your organs can do their jobs. Your blood vessels also carry carbon dioxide and other waste away for disposal.

It plays an important role in helping the body meet the demands of activity, exercise, and stress. It also helps maintain body temperature, among other things.
