Verified step by step guidance

Understand the term 'ventricular systole': Ventricular systole is the phase of the cardiac cycle during which the ventricles contract, pumping blood out of the heart.

Identify the structures involved in ventricular systole: During this phase, the ventricles contract to push blood into the major arteries.

Recognize the major arteries receiving blood during ventricular systole: The aorta receives blood from the left ventricle, and the pulmonary trunk receives blood from the right ventricle.

Differentiate between the structures listed in the problem: The coronary arteries supply blood to the heart muscle itself, the atria receive blood during diastole, and the vena cava are veins that return blood to the heart.

Conclude which structures receive blood during ventricular systole: Based on the understanding of the cardiac cycle, the aorta and pulmonary trunk are the correct structures that receive blood during ventricular systole.
