Systemic Circuit

Freshly oxygenated blood moves from the left atrium into the left ventricle. Contraction of the left ventricle forces this blood into the systemic circuit. This circuit includes the aorta and its branches that lead to all of the body tissues, as well as the companion system of veins that returns blood to the right atrium.

H Distinguish between the pulmonary and systemic circuits of the cardiovascular system.

^9 Trace a drop of blood through the pulmonary circuit from the right ventricle.
