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.
One primary function of the circulatory system is the transport of oxygen from the lungs to the cells. This is why the system has two basic parts: the pulmonary circulation, which takes blood to the lungs to pick up oxygen, and systemic circulation, which takes the oxygenated blood throughout the body.
