| Front | Describe the Cardiac Cycle on the left side |
|---|---|
| Back | - blood from pulmonary vein enters LA - LA fills with blood - bicuspid valve open - passive filling of LV - semi-lunar valve shut - atrial systole, atrial blood pressure increases - blood moves down pressure gradient into ventricles through open bicuspid valve - semi-lunar valve shut - ventricular systole - bicuspid valve closes to prevent backflow - ventricular blood pressure increases - semi lunar valve opens - blood moves down pressure gradient from LV into aorta |
