Detailed explanation-1: -Your aorta and pulmonary trunk (arteries) send blood out of your heart. Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your heart.

Detailed explanation-2: -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-3: -Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.

Detailed explanation-4: -Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body’s largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body.
