Detailed explanation-1: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart.
Detailed explanation-2: -Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve.
Detailed explanation-3: -Arteries are blood vessels that carry oxygenated blood to all parts of the body. They have thick muscular walls and have no valves in their inner linings. Veins carry deoxygenated blood and have thin muscular wall. They have valves in their inner lining to prevent the backward flow of blood.
