Verified step by step guidance

Understand the components of the circulatory system: The circulatory system is divided into three main circuits: systemic, pulmonary, and coronary.

Identify the function of each circuit: The systemic circuit carries oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart. The pulmonary circuit carries deoxygenated blood from the heart to the lungs and returns oxygenated blood back to the heart. The coronary circuit supplies blood to the heart muscle itself.

Recognize the major blood vessels involved: The aorta is the largest artery in the body and is part of the systemic circuit, carrying oxygenated blood from the left ventricle to the body. The vena cava consists of the superior and inferior vena cava, which are large veins that return deoxygenated blood from the body to the right atrium of the heart, also part of the systemic circuit.

Eliminate incorrect options: The lymphatic circuit is not part of the circulatory system in the context of blood circulation. The pulmonary circuit involves the pulmonary arteries and veins, not the aorta and vena cava. The coronary circuit involves coronary arteries and veins, which supply the heart muscle.

Conclude with the correct circuit: Since the aorta and vena cava are involved in transporting blood to and from the body, they are part of the systemic circuit.
