Final answer:
Systemic Blood Back-Flow Prevention
Step-by-step explanation:
Systemic Blood Back-Flow Prevention
Systemic circulation is the part of the circulatory system that carries blood between the heart and body. Oxygenated blood leaves the left ventricle of the heart through the aorta and travels through major systemic arteries to the various parts of the body. To prevent systemic blood back-flow, the heart has valves that ensure one-way flow of blood. The atrioventricular valves prevent back-flow from the ventricles to the atria, while the semilunar valves prevent back-flow from the arteries to the ventricles.
