No the way the valves of the heart are set up causes the blood to move in one direction only.
The valves open and close to allow the blood to flow only in only one direction.
yes
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.
No, semilunar valves control the flow of blood out of the heart.
The veins return blood from the body back to the heart, then out of the heart to the lungs where it is oxygenated, then back to the heart and carried back out into the body by arteries. The blood in the veins is blue but is seen through you skin as a dark green.
Valves in the heart help to keep the blood flowing in the right direction.
Valves are the "doors" which allow the proper amount of blood into each ventricle of the heart so it does not "explode" or push too much into the body. When high blood pressure occurs the culprit can be a defective valve that is leaking or failing to open and close properly. Not many people have that type of high blood pressure. There are many types of high blood pressure which doctors can determine by listening to the valves in the heart or elsewhere.
The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
up and down depends on the direction of the heart
There is no blood vessel that pumps blood. Only the heart pumps blood. The veins have one way valves that help bring blood back to the heart assisted by the contraction of skeletal muscles.
The reason why we need we need valves in our heart is because the valves in our heart will open and close. When the valves in our heart open, they allow blood to go into places in our body where blood is needed. When the blood passes through, the valve closes. They regulate the blood flow.

Yes. That is 'the' function of the heart valves or for that matter valves.
No, semilunar valves control the flow of blood out of the heart.
No, veins carry blood to the heart. Valves are in your heart, and they separate certain chambers, like the right atrium and right ventricle.
The part of the heart that opens when blood flows though is called the valve. There are four valves in the heart, two atrioventricular valves and two semilunar valves.
