what cause the aortic semilunar valve to close...greater pressure in the aorta than in the left ventricle
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
The aortic semilunar valve is auscultated by placing a stethoscope next to the sternum in the second intercostal space.
The blood flows through the aorta after exiting the left ventricle through the aortic valve.
The aortic semilunar valve is located between the left ventricle and the aorta.
Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.
Pulmonary semilunar valve (pulmonary valve)
pulmonary semilunar valve
there r two valves: aortic semilunar valve and pulmonary semilunar valve
Aortic Semilunar Valve
The aortic valve and pulmonary valve are collectively referred to as the semilunar valves due to their semilunar shape. These valves are located between the ventricles and the major arteries of the heart.
