Verified step by step guidance

Understand the basic function of the circulatory system, which involves the heart, blood vessels, and blood. The heart pumps blood through a network of arteries and veins, delivering oxygen and nutrients to tissues and removing waste products.

Review the role of arteries and veins in the circulatory system. Arteries typically carry blood away from the heart, while veins carry blood toward the heart. However, the oxygen content of the blood in these vessels can vary depending on their location in the circulatory system.

Examine the pulmonary circulation, where the pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs, and the pulmonary veins carry oxygen-rich blood from the lungs to the left atrium of the heart.

Consider the systemic circulation, where the left ventricle pumps oxygen-rich blood into the aorta and through the systemic arteries to the rest of the body. The systemic veins return deoxygenated blood to the right atrium of the heart.

Evaluate each statement based on the understanding of the circulatory system: Arteries do not always carry oxygen-rich blood (e.g., pulmonary arteries), the pulmonary veins do carry oxygen-rich blood, the left atrium receives oxygen-rich blood from the lungs, and the right ventricle pumps blood into the pulmonary circulation, not systemic.
