Atrioventricular (AV) valves prevent blood from flowing backward into the __________.
When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. When the ventricles relax, semilunar valves close to prevent blood from flowing back into the ventricles. The valve between the right ventricle and pulmonary trunk is the pulmonary semilunar valve. The valve between the left ventricle and the aorta is the aortic semilunar valve. When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. The valve between the left ventricle and the aorta is the aortic semilunar valve. When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. When the ventricles relax, semilunar valves close to prevent blood from flowing back into the ventricles. In the heart, there are valves to prevent back flow of blood. First there are the atrioventricular valves to prevent back flow back into the atria. Second there are the pulmonary valve and the semilunar valve to prevent back flow into the ventricle.

First there are the atrioventricular valves to prevent back flow back into the atria. The one-way nature of the left AV valve prevents blood flow from _________. The atrioventricular valves are one-way valves that allow blood to flow into the ventricle but prevent blood flow back into the atrium. This maintains the movement of blood forward, toward the systemic circulation. First there are the atrioventricular valves to prevent back flow back into the atria. Second there are the pulmonary valve and the semilunar valve to prevent back flow into the ventricle.

There are two semi-lunar valves also prevent the backward flow of blood from arota to the left ventricle (Aortic valve) and from the Pulmonary Artery to the right ventricle (the Pulmonary valve). The valves at the top of the heart are the semi lunar vavles. The atrioventricular valves (AV valves), which separate the atria from the ventricles, allow blood to flow from the atria to the ventricles, but prevent flow in the opposite direction. The right AV valves is called the tricuspid valve. The left AV valve is called the mitral valve.
