Ventricles pump blood out of the heart. Which types of vessels will be the first to contact the blood from the ventricles?

Blood leaves the ventricles through arteries: the right ventricle pumps blood into the pulmonary artery, and the left ventricle pumps it into the aorta. Therefore, arteries are the first vessels to contact blood pumped out of the ventricles. Atria receive blood returning to the heart, while capillaries and veins come later in circulation.
