Where does the sound of your heart pumping blood come from?
heart valves opening and closing
Opening and closing of the heart valves is caused by?
pressure gradients.
What produce the heart sounds heard with a stethoscope?
The valves opening and closing
How is a heartbeat generated?
it is valves in the heart opening and closing.
How does the disease affect the heart's mitral valve with RHD?
This infection causes swelling and muscle damage to the heart. It can also damage the heart valves in a way that keeps the blood from moving through the heart normally. The infection can cause heart valve leaflets to stick together, which narrows the valve opening. Also, the infection can scar the valves.
The heart valves are arranged with the?
valves in the heart are at the opening of the right and left auricle,poening of the right and left venticle and the closing of the right and left ventricle
What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
What causes the valves to open and close during the heart cycle?
By minute electrical singles produced by the heart itself to open and close the valves.
What causes the heart murmur?
Some murmurs are caused by heart valves that do not close completely.
What causes the lub-dup heart sounds that are heard with the stethoscope?
The cardiac sounds (typically described as lub-dub) are caused by the closing of the cardiac valves. The first sound (lub) is caused by the closing of the mitral and tricuspid valves and the second (dub) is caused by the closing of the aortic and pulmonic valves.
