Cardiac Cycle

HideShow resource information
Atrial Systole
AV valves open, semilunar valves closed. Atria contract, ventricles relax.
1 of 5
Early Ventricular Systole
Atria relax and ventricles contact. AV valves forced closed, semilunar valves still closed.
2 of 5
Late Ventricular Systole
Atria relax, and ventricles contract. AV valves remain closed, semilunar valves forced open.
3 of 5
Early Ventricular Diastole
Atria and ventricles relax. AV valves and semilunar valves closed, so atria being passively filling w/ blood.
4 of 5
Late Ventricular Diastole
Atria and ventricles relax. Atria passively fills with blood, as AV valves open and semilunar valves closed.
