The systemic circuit is that part of your circulatory system that carries blood away from your heart, delivers it to most of your organs and tissues, and returns it to your heart again. The systemic circuit is distinct from the pulmonary circuit, which only conducts blood between your heart and lungs.
A schematic circuit diagram represents the electrical system in the form of a picture that shows the main features or relationships but not the details. In a schematic circuit diagram, the presentation of electrical components and wiring does not entirely correspond to the physical arrangements in the real device.
The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle. The left ventricle is the pump for the systemic circuit, which provides the blood supply for the tissue cells of the body.
