Question

which path describes the movement of oxygenated blood leaving the heart? use the standard image of the heart to guide you.
a. left atrium → left ventricle → aorta
b. left ventricle → left atrium → pulmonary artery
c. right atrium → right ventricle → pulmonary artery
d. right ventricle → right atrium → aorta

Explanation:

Oxygenated blood returns to the left atrium from the lungs. It then moves to the left ventricle. The left ventricle pumps this oxygenated blood into the aorta for distribution to the body. In option B, the order of left ventricle and left atrium is wrong (should be left atrium first). In option C, the right side of the heart deals with de - oxygenated blood. In option D, the order of right ventricle and right atrium is wrong (should be right atrium first) and the aorta is not the correct vessel for the right side of the heart.

Answer:

A. left atrium → left ventricle → aorta
