Verified step by step guidance

Understand the basic flow of blood in the circulatory system: Blood flows from the body to the heart, then to the lungs, back to the heart, and finally out to the body again.

Identify the role of pulmonary arteries: These vessels carry blood from the right ventricle of the heart to the lungs. Since this blood is coming from the body, it is oxygen-poor and needs to be oxygenated in the lungs.

Consider the pulmonary veins: These vessels carry oxygen-rich blood from the lungs back to the left atrium of the heart, so they do not contain oxygen-poor blood.

Examine the aorta: This is the main artery that carries oxygen-rich blood from the left ventricle of the heart to the rest of the body, so it does not contain oxygen-poor blood.

Analyze the left atrium: This chamber of the heart receives oxygen-rich blood from the pulmonary veins, so it does not contain oxygen-poor blood. Therefore, the correct location for oxygen-poor blood is the pulmonary arteries.
