Four valves are usually present in a mammalian heart and together they determine the pathway of blood flow through the heart. The four heart valves open and close in response to pressure changes that occur in the ventricles during each cardiac cycle.

The first heart sound is due to closure of the mitral and tricuspid valves. These valves open and close during the cardiac cycle to direct the flow of blood through the heart chambers and out to the rest of the body.

When the pressure in the left ventricle exceeds the pressure in the aorta, the aortic valve opens and blood flows from the left ventricle into the aorta. The heart valves open and close passively because of pressure differences on either side of the valve.

The atrioventricular valves are located between the atria and the ventricles. A heart sound is heard when a heart valve closes.

Aortic Valve StenosisSource: medmovie.com

When pressure is greater behind the valve, the leaflets are blown open and the blood flows through the valve. This causes the pulmonary valve to open and the tricuspid valve to close.

The second heart sound, s 2, is the sound of the closing of the semilunar valves during ventricular diastole and is described as a “dub” (figure 19.3.3). During diastole, both atrioventricular valves.

The Atrioventricular Valves Are Located Between The Atria And The Ventricles.

Between the right ventricle and the pulmonary artery, there is the pulmonary valve. When pressure is greater behind the valve, the leaflets are blown open and the blood flows through the valve. This causes the pulmonary valve to open and the tricuspid valve to close.

Valve Is Pushed Open, Papillary Muscles Relax, Chordae Tendinae Slacken.

Blood flows out from the right ventricle to the lungs before it is returned to the left atrium as fresh, oxygenated blood. It is a progressive disease causing a narrowing of the aortic valve which reduces its ability to fully open and close. When the ventricles relax, their pressures drop below those of the atria, pulmonary trunk artery, and aorta.

The Heart Valves Open And Close Passively Because Of Pressure Differences On Either Side Of The Valve.

There are two av valves: In both cases, as the valves close, the openings within the atrioventricular septum guarded by the valves will become reduced, and blood flow through the opening will become more turbulent. The aortic valve is open.

Closed Open Diseased Aortic Valve Closed Open Aortic Stenosis Is One Of The Most Common And Serious Valve Disease Problems.

Aortic stenosis, or as, restricts the blood flowing out of the left ventricle. It consists of three cusps (anterior, septal and posterior), with the base. During diastole, both atrioventricular valves.

Heart Valves Are Formed From Elastic Connective Tissue Which Provides The Flexibility Needed To Open And Close Properly.

Open and close in response to differences in blood pressure on their two sides. These include the aortic valve and the pulmonary valve leading to the aorta and pulmonary trunk respectively. These valves open and close during the cardiac cycle to direct the flow of blood through the heart chambers and out to the rest of the body.
