It is just called the circulatory system, and it is one of my favorites to learn about.

name two kinds of circulation through the heart
In double circulation there is complete segregation of oxygenated and deoxygenated blood. Because of this the blood passes twice through the heart in one cycle of circulation hence the name double circulation. This is necessary for optimum oxygen utilization as humans are warm blooded animals and need extra energy to maintain their body temperature

systemic circulation
The heart and blood vessels are part of the cardiovascular system. Cardio- or cardiac refer to the heart. Vascular refers to the blood vessels. Circulation or circulatory refers to the movement of blood through the vascular system.
The systemic circulation connects the heart to all body parts. The pulmonary circuit connects the heart to the lungs.
The heart is two side-by-side pumps, each serving a separate blood circuit: - The blood vessels that carry blood to and from the lungs form the pulmonary circuit, which serves gas exchange. - The blood vessels that carry the functional blood supply to and from all body tissues constitute the systematic circuit. Pulmonary circuit - the right side of the heart is the pulmonary circuit pump. Blood returning from the body is relatively oxygen-poor and carbon dioxide-rich. It enters the right atrium and passes into the right ventricle, which pumps it to the lungs via the pulmonary trunk. In the lungs, the blood unloads carbon dioxide and picks up oxygen. The fresh oxygenated blood is carried by the pulmonary veins back to the left side of the heart (left atrium). NOTICE how unique this circulation is. Typically, we think of veins as vessels that carry blood that is relatively oxygen-poor to the heart and arteries as transporters of oxygen-rich blood from the heart to the rest of the body. Exactly the opposite condition exists in the pulmonary circuit. Systematic circuit - the left side of the heart is the systematic circuit pump. Freshly oxygenated blood leaving the lungs is returned to the left atrium and passes into the left ventricle which pumps it into the aorta. From there the blood is transported via smaller systemic arteries to the body tissues, where gases and nutrients are exchanged across the capillary walls. Then the blood once again loaded with carbon dioxide and depleted of oxygen, returns through the systemic veins to the right side of the heart, where it enters the right atrium through the superior and inferior venae cavae.
