Series of events that constitute a complete heartbeat. Pressure in heart changes. 70% of blood enters ventricles prior to atrial contraction. 30% of the returning blood is pushed in the ventricles.
Systole is the last stage of a heart beat. It happens right after diastole, when the heart refills with blood. During systole, the heart's two ventricles contract (squeeze). (The ventricles are the largest parts of the heart, which pump blood to the body and lungs.) During systole, the heart muscle gets an automatic electrical signal that tells the heart to contract (squeeze). This makes the blood flow out of the heart.
