There are actually four valves in the heart: The tricuspid valve, mitral valve, pulmonary semilunar valve, and aortic semilunar valve. If you needed to list three different types of valves, you could consider both semilunar valves as one configuration type. Then you would have: Tricuspid valve, bicuspid (aka mitral) valve, and semilunar valves.
The three coronary arteries / main vessels of the heart are the circumflex, the left anterior decending and the right coronary artery
the blood, blood vessels and the heart are the three main elements of the circularatory system. Hope that helped :)

keep you alive! they bring blood to the heart so it can get circulated round the body and lungs again
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
Veins. Vessels that carry it from the heart are called arteries.

The two main blood vessels leading out of the heart are the pulmonary trunk and the aorta.

The five main parts are the arteries, capillaries, veins, heart and most people don't count blood but blood is also one!
1) 4 chambers of the heart 2) Aorta 3) blood vessels 4) capillaries 5) blood 6) veins

The main organs of the respiratory system are the lungs. The main organs of the circulatory system are the heart and blood vessels.
There are three main types of blood vessels. The arteries(red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poorbloodback to the heart.
