What are the primary parts of the systemic circuit, and in what order does blood run through them?
the left atrium and ventricle of the heart ® blood vessels
the left ventricle and the aorta ® arteries
the left atrium and ventricle of the heart ® the aorta
the left ventricle and the aorta ® blood vessels

the left ventricle and the aorta ® blood vessels

Explanation:

In systemic circulation, blood is taken from the heart to the tissues and then back to the heart. This circulation begins when blood leaves the left ventricle through the aorta. From this artery come branches that irrigate the whole body. In the blood capillaries, the blood makes gaseous exchanges with the tissue cells and becomes rich in carbon dioxide.

After gas exchange, blood is collected by the venules that carry the blood to the upper and lower vena cavae. The vena cava carry blood to the heart, flowing into the right atrium.

Thus we can say that the correct answer to your question is "the left ventricle and the aorta ® blood vessels".
