#Unit 7. System Physiology – Animal

During isovolumetric Ventricular contraction, the volume of the ventricle does not change because all valves are closed.

#Unit 7. System Physiology – Animal

Period of isovolumetric ventricular contraction lasts, until the pressures in the left and right ventricles,exceed the pressures in the aorta & pulmonary artery.

Rapid Ventricular Ejection When ventricular pressure becomes greater than aortic pressure, the aortic valve opens (left heart).

Rapid Ventricular Ejection

Blood is rapidly ejected from the left ventricle into the aorta through aortic valve, driven by the pressure gradient between the left ventricle and the aorta.

atrial filling begins 

left atrial pressure slowly increases as blood is returned to the left heart from the pulmonary circulation.
