Systole

For other uses, see Systolic geometry.
The cardiac cycle at the point of beginning a ventricular systole, or contraction: 1) newly oxygenated blood (red arrow) in the left ventricle begins pulsing through the aortic valve to supply all body systems; 2) oxygen-depleted blood (blue arrow) in the right ventricle begins pulsing through the pulmonic (pulmonary) valve en route to the lungs for reoxygenation.

Systole (/ˈsɪstəli/ SIST-ə-lee) is the part of the cardiac cycle during which some chambers of the heart contract after refilling with blood.[1] Its contrasting phase is diastole, the relaxed phase of the cardiac cycle when the chambers of the heart are refilling with blood.
