- It also allows the flow of blood in one direction. After the oxygenated blood flows from the atrium to the ventricle the valve closes to prevent the blood from flowing back. This valve has only 2 flaps which give it the name bicuspid.

Right atrioventricular valve (Tricuspid valve) The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava. These are large veins that transport deoxygenated blood from the body back to the heart.

- Best Answer: The tricuspid valve regulates the opening between the right atrium and the right ventricle. As the right atrium contracts, the tricuspid valve opens, allowing blood to eject into the right ventricle. When the atrium is finished contracting, the tricuspid valve closes, preventing a backwash of blood.Source(s): bioguy · 7 years ago.s the right atrium contracts, the tricuspid valve opens, allowing blood to eject into the right ventricle.

Roles of Your Four Heart Valves Here are the four valves in order of circulation: TRICUSPID VALVE. Closes off the upper right chamber (or atrium) that holds blood coming in from the body. Opens to allow blood to flow from the top right chamber to the lower right chamber (or from right atrium to right ventricle). Prevents the back flow of blood from the ventricle to the atrium when blood is pumped out of the ventricle.

Anatomy of the Heart: Valves Tricuspid Valve: Heart valve located between the right atrium and the right ventricle. When closed, it allows oxygen-depleted blood returning to the heart from the venae cavae to fill the right atrium. It also prevents the back flow of blood as it is pumped from the right atrium to the right ventricle.

- Diagram of the blood flow path in the heart. Now that blood is freshly oxygenated from its trip to the lungs, it returns to the left atrium of the heart and passively flows through the bicuspid (or mitral valve). This is the valve that separates the left atrium and the left ventricle.

- The aortic valve allows oxygen-rich blood to flow from the heart to the aorta. It prevents the blood from flowing back from the aorta into the heart when the pumping chamber relaxes. Bicuspid aortic valve is present at birth (congenital).

The Functions of the Heart This de-oxygenated blood passes through the tricuspid valve into the right ventricle. This blood is then pumped under higher pressure from the right ventricle to the lungs via the pulmonary artery. The left-hand side of the heart receives oxygenated blood from the lungs (via the pulmonary veins) into the left atrium.This oxygenated blood then passes through the bicuspid valve into the left ventricle. It is then pumped to the aorta under greater pressure (as explained below).he main functions of the heart can be summarised as follows: The right-hand side of the heart receives de-oxygenated blood from the body tissues (from the upper-and lower-body via the superior vena cava and the inferior vena cava, respectively) into the right atrium.

- The tricuspid valve prevents back flow of blood from the right ventricle into the right atrium during ventricular systole when it closes and allows blood to flow from right atrium into right ventricle during ventricular diastole when it opens. This valve is weakened by drug abuse.

Tricuspid Valve Disease What is tricuspid valve disease? For more information on valve disease and its treatment, see Valve Disease. The tricuspid valve is located between the right atrium (top chamber) and right ventricle (bottom chamber). Its role is to make sure blood flows in a forward direction from the right atrium to the ventricle. Tricuspid valve disease refers to abnormal function of the tricuspid valve. Two types of tricuspid disease include: Tricuspid regurgitation - the valve is leaky or doesn't close tight enough, causing blood to leak backwards across the valve; Tricuspid stenosis - the valve leaflets are stiff and do not open widely enough, causing a restriction in the forward flow of blood.

What valve separates the right atrium and the right ventricle? The right atrioventricular valve (or right AV valve), also called the tricuspid valve, (for its three leaflet lobes) controls the flow of blood between the right atrium and right ventricle. (The opening itself is the right atrioventricular canal.) It prevents dexoygenated blood from regurgitating back into the right atrium. The vale is called tricuspid because of its three leaflets; it must be noted however, that the tricuspid valve can contain between two and four leaflets.

Aortic Valve Disease What is Bicuspid Aortic Valve?Healthy aortic valves have three cusps (or leaflets) that regulate blood flow from the heart’s left ventricle to the aorta.t is the most common congenital heart disorder, impacting both the aortic valve (which controls the flow of blood into the aorta) and the thoracic aorta (the major vessel that sends blood throughout the body).

Why the bicuspid valves have 2 flaps and the tricuspid valves have 3 flaps? bicuspid valves prevents the backflow of blood from the left ventricle. because there are two ventricles in the heart, left and right. the left one consist of oxygenated blood and the right one consist of deoxygenated blood so it will not mix up thru the present of bicuspid and tricuspid valve.icuspid valves prevents the backflow of blood from the left ventricle. because there are two ventricles in the heart, left and right. the left one consist of oxygenated blood and the right one consist of deoxygenated blood so it will not mix up thru the present of bicuspid and tricuspid valve.

What Is the Function of the Semilunar Valves? The function of the two semilunar valves of the heart, the aortic valve and the pulmonary valve, is to allow blood to be forced into the arteries from the ventricles and to prevent blood from flowing back from the arteries into the ventricles. The closure of these two valves creates the second heart sound of a heartbeat.

Heart valve 1 The two atrioventricular (AV) valves, the mitral valve (bicuspid valve), and the tricuspid valve, which are between the upper atria and the lower ventricles. 2  The two semilunar (SL) valves, the aortic valve and the pulmonary valve, which are in the arteries leaving the heart. heart valve normally allows blood to flow in only one direction through the heart. The four valves commonly represented in a mammalian heart determine the pathway of blood flow through the heart. A heart valve opens or closes incumbent on differential blood pressure on each side.

- Each side of your heart uses an inlet valve to help move blood between the atrium and ventricle. The tricuspid valve does this between the right atrium and ventricle. The mitral valve does this between the left atrium and ventricle. The lub is the sound of the tricuspid and mitral valves closing. Each of your heart's ventricles also has an outlet valve. The right ventricle uses the pulmonary valve to help move blood into the pulmonary arteries. The left ventricle uses the aortic valve to do the same for the aorta. The DUB is the sound of the aortic and pulmonary valves closing.

Bicuspid Aortic Disease A normal aortic valve (see below) has three leaflets (also known as flaps or cusps). These open and close to control the flow of blood into the aorta from the left ventricle of the heart as it beats. When the flaps come together as the valve closes, the shape is like a circle divided into thirds. The mitral valve may leak blood due to bicuspid leaflets. 2  One of the three layers of the wall of the aorta becomes thin and weak. 3  As a result, the aorta cannot stretch and contract properly when the heart beats and pumps blood into the aorta.
