Final answer:
Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart, completing the pulmonary circuit.
Step-by-step explanation:
The statement that correctly describes the cardiovascular pulmonary circuit is that pulmonary veins carries oxygenated blood. In the pulmonary circuit, after the gas exchange process in the alveoli of the lungs where carbon dioxide diffuses into blood and is expelled while oxygen is absorbed, the now oxygen-rich blood is returned to the heart via the pulmonary veins.
It travels to the left atrium, then to the left ventricle which pumps it through the aorta, and finally, it circulates throughout the body. The options mentioning the aorta carrying deoxygenated blood and the left ventricle pumping blood to the lungs are incorrect because the aorta carries oxygenated blood and the right ventricle pumps blood to the lungs.
