A murmur would occur during the lubb portion of the cycle if the AV valves were not closing properly. Most heart murmurs do not cause the patient any problems.

at the end
The closing of the mitral and tricuspid valves create the "lubb" and the closing of the semilunar valves creates the "dubb"
Reed Valves.
Pulmonary and aortic valves are semilunar valves having three semilunar cusps each. these valves open with the free ends facing the vessels when the heart contracts and closes when heart relaxes thus preventing regurgitation
generally speaking if it has valves its a 4 stroke 4 cycle engine......if it doesnt have valves then it is a two stroke 2 cycle...................
closed and closed
Pulse (pulse = to beat) or Complete Cardiac Cycle (beginning of one heartbeat until the beginning of the next) are two medical term for "heartbeat". Listen to your heartbeat and you might distinguish two sounds. The first sound is the closing of the upper atrioventicular valves. The second sound is the closing of the semilunar valves. This is the pushing of the blood out of the heart. Between beats, the heart is filling with blood and preparing for another push or pulse.
By minute electrical singles produced by the heart itself to open and close the valves.
yes
true
the opening and clsoing of valves that creates two beats
