Answer:

TRUE

Explanation:

In the cardiovascular system, the blood flows from high pressure to low pressure.

In the ventricular ejection phase, when the muscles of the ventricles contract, the pressure gradient in ventricles rises. This increases in the pressure in the ventricles exceeds the pressure in the pulmonary artery and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.
