Vedclass · Answer

(B) Systole refers to the phase of contraction of the heart chambers.In the cardiac cycle,the term 'systole' generally refers to ventricular systole,where the ventricles contract to pump blood into the aorta and pulmonary artery.Auricles (atria) and ventricles do not contract simultaneously; they contract in a coordinated sequence to ensure efficient blood flow.Therefore,the auricles and ventricles contract separately during the cardiac cycle.
