S1 (“lub”) is when the AV values of your heart close and blood is pushed out of the heart to the rest of the body. This is called. • S2 (“dub”) is when the semilunar values of the heart closes and the heart fills with blood. This is called diastole.

In the following six chapters the individual phases of the cardiac cycle are described. The description contains: . Mechanical events in the heart (the contraction on pictures is represented by a colour change of the myocardium). Pressure and volume changes in both the atria and the ventricles.
The two semilunar (SL) valves are present in the arteries leaving the heart; they prevent blood from flowing back into the ventricles. The sound heard in a heart beat is the heart valves shutting.
