What are the hearts two atrioventricular valves and two semilunar valves?
Tricuspid valve has three flaps and it is located between the right auricle and right ventricle. It prevents the blood from flowing back into the auricle. The mitral or bicuspid valve is situated between left auricle and left ventricle. It has two flaps which help in maintaining the blood flow in one direction (from left auricle to left ventricle). Tricuspid and bicuspid valves are together called auriculo-ventriclar valves. Semilunar valves has flap which resembles half moon. Pulmonary semilunar valve keep the direction of blood flow from right ventricle to lungs and aortic semilunar valve keep the direction of blood flow from left ventricle to aorta.
How many chambers are there in the human heart and list their names?
The heart has four chambers, the right and left atriums and the right and left ventricles. The artiums fill with the blood arriving from the body. The ventricles pump the blood out. The right ventricle pumps de-oxygenated blood to the lungs while the left ventricle pumps oxygenated blood to the rest of the body.
Why are the valves at the start of the aorta called semilunar valves?
Because there are crescent shaped, like half moons :)
How do you explain the function of the heart valves?
enforce a one way blood flow through the heart chambersthe valves prevent the blood from going backwards. they keep the blood flowing forwards! we just dissected a heart in science today so i know for sure thats what they do :)
What is the bottom half of the heart called?
right ventricle Ventricles, left and right

How do the valves between the atria and ventricles control the direction of blood flow?
The heart contains valves to prevent the backflow of blood. The right half of the heart has a "Triscupid Valve" and the left half of the heart has a "Biscupid Valve".
What prevents oxygenated blood from mixing with deoxygenated blood?
there are atrioventricular valves. Between the right atrium and right ventricle there is the tricuspid valve and between the left atrium and left ventricle there is the bicuspid (mitral) valve. When atria contract the valves open and when the ventricles contract they close.
What role does the right half of the heart play?
your right half of the heart collects the blood from the body and pumps it to the lungs to collect oxygen.
What valve in the body is not shaped like a half moon?
I would assume you mean the tricuspid valve in the heart? Most other blood vessel valves are described as "semi-lunar", meaning they look like a half-moon, have two parts and when they close they completely block the vessel they're in. The tricuspid valve in the heart is composed of three pieces, so they would not be shaped like a half-moon.

What is meant by eustachius valve?
The Eustachian valve is a remnant structure in the heart that is sometimes present in fetal development but typically regresses before birth. It is a flap of tissue located in the right atrium near the opening of the inferior vena cava. In some cases, the Eustachian valve can be associated with certain congenital heart abnormalities.
How do you explain the function of the heart valves?

What are the lyrics to 'Heart of Your Heart'?
I was born in the arms of imaginary friends Free to roam, made a home out of everywhere I've been Then you come crashing in, like the realest thing Trying my best to understand all that your love can bring Oh, half of my heart's got a grip on the situation Half of my heart takes time Half of my heart's got a right mind to tell you That I can't keep loving you (can't keep loving you) Oh, with half of my heart I was made to believe I'd never love somebody else Made a plan, stay the man who can only love himself Lonely was the song I sang, until the day you came Showing me another way and all that my love can bring Oh, half of my heart's got a grip on the situation Half of my heart takes time Half of my heart's got a right mind to tell you That I can't keep loving you (can't keep loving you) Oh, with half of my heart With half of my heart Your faith is strong But I can only fall short for so long Down the road, later on You will hate that I never gave more to you Than half of my heart But I can't stop loving you I can't stop loving you I can't stop loving you I can't stop loving you I can't stop loving you With half of my . . . Half of my heart Oh, half of my heart Half of my heart's got a real good imagination Half of my heart's got you Half of my heart's got a right mind to tell you That half of my heart won't do Half of my heart is a shotgun wedding to a bride with a paper ring And half of my heart is the part of a man who's never truly loved anything Half of my heart, oh, half of my heart Half of my heart, oh, half of my heart Half of my heart, oh, half of my heart Half of my heart
Why is half of the heart blue and half red?
Because the right side of your heart pumps deoxygenated blood and the left side pumps oxygenated blood.
Compare the function of left half of the heart with the right half?
they both pump oxygen blood through the blood
