Circulatory System. This system is made up of the heart, blood, blood vessels, and lymphatics. It is the bodyâs delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
While many view the circulatory system, also known as the cardiovascular system, as simply a highway for blood, it is made up of three independent systems that work together: the heart (cardiovascular); lungs (pulmonary); and arteries, veins, coronary and portal vessels (systemic), according to the U.S National Library of Medicine (NLM).
