Detailed explanation-1: -A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood. In fact, your pulmonary arteries are the only arteries in your body that carry oxygen-poor blood.
Detailed explanation-2: -In the pulmonary circuit, the pulmonary veins transport blood from the lungs to the left atrium of the heart. This blood has a high oxygen content because it has just been oxygenated in the lungs. Systemic veins transport blood from the body tissue to the right atrium of the heart.
Detailed explanation-3: -(d) high in oxygen, low in carbon dioxide. Normally, arteries carry oxygenated blood away from the heart and veins return deoxygenated blood back to the heart. However, the pulmonary arteries and pulmonary veins are the exception to this.
