The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.

What structures prvents the flow of blood back into the heart after the venricles contract?
Valves prevent the backflow of blood, in this case the semilunar valves stop blood flowing back into the heart.
Which structures carry blood back to the heart?
The veins carries blood from the body to the heart.
Where do venous valves channel blood?
They prevent back flow and help to return blood to the heart.
What tube like structures carry dexonated blood back to heart?
I think they're arteries.
Valves inside the veins prevent blood from flowing where?
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
What is the purpose of valves in blood vessels?
Valves are primarily found in veins. They are important because when blood is returning to the heart from places like the feet, they are moving against gravity. In order to prevent the blood from falling down to the feet as it rises back to the heart, valves are in place in order to prevent the blood from flowing backward.
What structures of the keep blood flowing in one direction?
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.

Back to the heart! Answered By Alex Usovich
Do atrioventricular vales prevent backflow into the heart?
yes, they get it back by pumping blood to the 4 parts of your heart. when you inhale, it makes rich blood when you exhale it takes out poor blood which turns into carbon dioxide.
What are the fibrous structures in the heart that prevent prolapse of the cuspid valves?
Chordae tendineae - attached to the valves between both atria and ventricles... these structures are attached to papillary muscles in the bottom of the ventricles. these contract when the valves contract, this keeps the blood from going back up into the atria.
What blood vessel has bigger activities?
Blood vessels are structures that carry the blood from the heart to all the tissues of the body and then back to the heart.arteries: large blood vessels running away from the heartveins: large blood vessels running toward the heart
