Question 1

how is the backward flow stopped in some veins....like it is stopped in the biscuspid valve...?

Accepted Answer

Valves: There are one-way valves in the large veins that prevent backward flow.  Also, the pressure running through the entire circulatory system and the compression of the veins by muscles helps the blood move along.

Question 2

how does the bicuspid valve function?

Accepted Answer

May be normal: The aortic valve is comprised of three leaflets, or cusps, that swing open and closed. Approximately 1% of the population is born with only 2 cups. These swing open and shut in a similar fashion. Depending on the precise architecture of the 2 cusps, there may be increased turbulence of blood flow through the valve, and over time more wear and tear leading to thickening/obstruction, or leaks.

Question 3

what is the function of the bicuspid valve?

Accepted Answer

Mitral valve: Bicuspid means "two leaflets". The only "normal" bicuspid valve in the heart is the mitral valve. It sits between the left atrium and left ventricle. The valve opens to fill the left ventricle during diastole and closes when the ventricle contracts (systole).
The aortic valve is normally tricuspid but some people are born with an abnormal and bicuspid valve which may narrow later in life...

Question 4

what is another name for the bicuspid valve?

Accepted Answer

The mitral valve: The only valve normally having just two cusps is the mitral valve which therefore is sometimes called the bicuspid valve.

Question 5

what happens if someone's bicuspid valve does not close properly?

Accepted Answer

Aortic insufficiency: When an aortic valve (bicuspid or a normal tricuspid valve) does not close properly, insufficiency or regurgitation ("leaking") results. When mild, this does not have clinical effects, but when severe it can compromise cardiac function.

Question 6

bicuspid arotic valve?

Accepted Answer

Your question?: You named a valve of the heart. The aortic valve is one of the four valves of the heart. It normally has three leaflets, although in 2% of the population it is found to congenitally have two leaflets.

Question 7

what is the location of the mitral bicuspid valve?

Accepted Answer

Mitral location: Calling it a bicuspid mitral valve is redundant. The mitral valve has two (bi) leaflets and was named for its appearance similar to a bishop's miter. It is located between the left atrium and ventricle and its function is to prevent blood from flowing back into the left atrium when the left ventricle contracts and pumps its content into the aorta.

Question 8

how can the bicuspid and tricuspid valves open and close?

Accepted Answer

Pressure gradients: The valve leaflets shown in the picture are very thin- like cloth.  When the heart relaxes and pump, pressure gradients open and close the valves.  I suggest you watch this video: http://www.youtube.com/watch?v=rguztY8aqpk

Question 9

where does blood enter after it leaves the bicuspid valve?

Accepted Answer

Aorta: The aortic valve is the last valve crossed by the blood as it leaves the heart.  Once blood leaves the heart, crossing the aortic valve, it enters the aorta (the largest artery of the body).

Question 10

what is the difference between the mitral and bicuspid valves?

Accepted Answer

Nothing - same: The mitral valve or left atrio-ventricular valve is a bicuspid valve. The latter simply means a valve with two leaflets.  That is the normal state.  A tricuspid valve (3 leaflets) is normally the morphology of the right atrio-ventricular and aortic valves.
