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.
The heart and the lungs are the primary organs of the circulatory system. The lungs are responsible for adding oxygen to blood. This oxygen-rich blood is then pumped to the heart, which then circulates it through the arteries to all the tissues throughout the body.
