Q

Explain what is going on during the Period of Ventricular filling

Q

Explain what is going on during Ventricular Systole (S1)

A

The ventricles are being electrically stimulated causing them to contract. The pressure in the ventricles force the opening of the semilunar valves which then open, which then causes blood to expel from the ventricles

Q

Explain what is occurring during Isometric Relaxation (S2)

A

the pressure in the aorta and pulmonary artery are more than the ventricles causing the valves to close. Simultaneously, the atria are filling which then have an increased pressure the valves can open, causing the process to repeat
