Why does mitral valve prolapse occur more often than tricuspid prolapse?
Because there is much more pressure on the mitral valve.Mitral valve prolapse occur more often than tricuspid valve prolapses because the mitral valve is attached to the left ventricle by two chordae tendinae, whereas the tricuspid valve adheres to the right ventricle via three chordae tendinae. Thus, the tricuspid valve has more stability and is less likely to prolapse.
Are the papillary muscles and chordae tendineae in the right ventricle also present in the left ventricle?
yes
Why is the wall of the left ventricle thicker than that of the right ventricle?
The right ventricle just receive the blood and pump it into the lungs only, but the left ventricle pump the blood to all round the body, to do the ventricle wall is more thicker, that's why the left ventricle have thicker wall..... Hope I helped you!! (Ivy Yumi Y)
Which chamber of the heart pumps blood through the aorta to the body?
It comes from the left ventricle out through the aorta.
Is damage to the right ventricle or left ventricle more serious?
It is a common misconception that damage to the left ventricle OS the most serious damage a heart can take. This is because the left ventricle is the chamber that pumps the blood aroundthe blody. And true enough, if it takes too much damage the systems of the body will not receive any oxygen. But if the right venrticle is damaged too much then the deoxygenated blood wont get to lungs and so the body systems will still receive no oxygen. So neither is worse, instead it is the degree of damage to the chamber that determines how serious it is.

What would happen if the chordae tendineae were cut?
If the chordae tendineae were cut, the valves in the heart would not be able to close properly, leading to backflow of blood. This would result in decreased efficiency of the heart's pumping action and could lead to symptoms of heart failure. Surgery would be required to repair or replace the damaged chordae tendineae.
Are the papillary muscles and chordae tendineae in the right ventricle also present in the left ventricle?
yes
What are the white strings in a human heart function?
Scientifically known as Chordinae Tendinae, these are tendons responsible for linking the papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. As the papillary muscles contract and relax, the chordae tendineae transmit the resulting increase and decrease in tension to the respective valves, causing them to open and close.

Name the structure between the left atrioventricular valve and the papillary muscle?
The structure between the left atrioventricular valve and the papillary muscle is the chordae tendineae.
What are the functions of valves in the circulatory system and where are they found?
There are 4 valves in your heart (2 atrioventricular and 2 semilunar). There is an AV valve between the right atrium and the right ventricle (Right AV valve or tricuspid valve) and an AV valve between the left atrium and the left ventricle (Left AV valve or bicuspid valve). There are also two semilunar valves; one between the right ventricle and the lungs (pulmonary semilunar valve) and one between the left ventricle and the aorta (aortic semilunar valve). The main purpose of the valves is to prevent backflow of blood in the heart. There are things called the chordae tendinae and papillary muscle that help control the opening and closing of the valves as blood flows through them. There are also valves in the veins. These keep the blood from flowing backwards as the blood pressure is very low.
Which chamber of the heart pumps blood through the aorta to the body?
It comes from the left ventricle out through the aorta.
The atrioventricular valves hAVe muscles and tendons associated with them. Name and describe the muscles and tendons and how they function to assist the AV valves?
The tendon chords are called chordae tendinae and they attach the tricuspid (right AV) and mitral (left AV) valves to muscles called papillary muscles, which are attached to the ventricular wall muscles. When the ventricle contracts, the papillary muscles also contract, pulling the valves closed and preventing the backwards flow of blood into the atria.
Is damage to the right ventricle or left ventricle more serious?
It is a common misconception that damage to the left ventricle OS the most serious damage a heart can take. This is because the left ventricle is the chamber that pumps the blood aroundthe blody. And true enough, if it takes too much damage the systems of the body will not receive any oxygen.

Which chamber or the heart does the aorta attach to?
left ventricle
Is left ventricle an artery?
A left ventricle is not an artery.
