Cardiac Cycle: 1st Systole Phase. During the systole phase, the right ventricle receives impulses from the Purkinje fibers and contracts. The atrioventricular valves close and the semilunar valves open. The de-oxygenated blood is pumped into the pulmonary artery.
the pressure ramp caused by slow blood flow from the pulmonary veins into the left atrium when the mitral valve is closed. briefly describe the atrial v wave. period of rapid filling, diastasis, atrial systole. list the 3 events that occur when the left and right ventricles fill during diastole.
