Final answer:

During ventricular systole, the aorta and pulmonary artery receive blood. The aorta gets it from the left ventricle, and the pulmonary artery from the right ventricle. The atria receive blood during diastole, not systole.

Step-by-step explanation:

During ventricular systole, the ventricles of the heart contract to pump blood out of the heart. There are two main vessels that receive blood during this phase:

  • The aorta receives oxygenated blood from the left ventricle and distributes it to the systemic circuit, which serves the body's tissues.
  • The pulmonary artery receives deoxygenated blood from the right ventricle and carries it to the lungs for oxygenation, which is part of the pulmonary circuit.

The atria, specifically the left atrium and the right atrium, do not receive blood during ventricular systole; instead, they receive blood during the heart's diastole phase when the ventricles are relaxed.
