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 circulatory system begins in your right atrium, the upper right-hand chamber of your heart. As blood moves through your heart, it passes through each of the four chambers (upper right, lower right, upper left, lower left), takes a quick detour to the lungs to get rid of carbon dioxide and pick up oxygen, and ends up in the lower left-hand chamber, called the left ventricle.
