Why the first and second heart sounds different in intensity or pitch?
Popah
One is the heart pumping blood out, into the body. The second is the heart's intake beat; moving more blood into itself for the next pump. The intake is at less pressure than the pump out, so it is less strain on the muscle and sounds lighter.
