Those Heartbeat Graphs A hilarious science meme

Highest pressures are during systole Atria Ventricle Aorta Ventricular Systole Highest pressures are during systole Diastole Atrial Systole

Aorta Ventricle Atria Blood forced out of ventricles Blood forced into Aorta Ventricles empty All blood forced into ventricles Atrium begins filling with blood

Aorta Ventricle Atria Semilunar valve closes Semilunar valve opens Semilunar valves at the top – The moon can be seen high in the sky. AV valve closes AV valve opens

Aorta Ventricle Atria Ventricular Systole Diastole Atrial Systole Semilunar valve closes Ventricular Systole Blood forced out of ventricles Blood forced into Aorta Semilunar valve opens Ventricles empty All blood forced into ventricles AV valve closes AV valve opens Diastole Atrial Systole Atrium begins filling with blood
