Question 5 2 pts The pulmonary semilunar valve is forced open when: pressure in the left ventricle is higher than pressure in the aorta pressure in the right ventricle is higher than pressure in the pulmonary artery pressure in the left ventricle is higher than pressure in the left atrium pressure in the left ventricle is lower than pressure in the left atrium pressure in the right ventricle is lower than pressure in the right atrium Question 6 2 pts Which occurs during isovolumetric ventricular contraction? Rapid filling of the ventricles occurs. No blood enters or leaves the ventricles The maximum volume of blood is ejected. Ventricular pressure reaches its maximum value of the cardiac cycle. The pressure in the ventricles decreases while the pressure in the atria increases.

Explanation / Answer

1.The pulmonary semilunar valves open when the pressure in the right ventricle is higher than pressure in pulmonary artery.

2.What occurs during isovolumetric ventricular contraction?

Ans VENTRICULAR PRESSURE REACHES ITS MAXIMUM VALUE OF THE CARDIAC CYCLE.
