The Cardiac Cycle Phase 1 - Atrial Systole Made EASY!!

This video delves into the cardiac cycle, focusing on atrial systole. It explains the role of the SA node in initiating atrial contraction, the resulting pressure changes, and the movement of blood into the ventricles. The concept of end diastolic volume is introduced, setting the stage for understanding stroke volume in future videos.
