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 blood into the aorta. Therefore, arteries are the first vessels to contact blood pumped from the ventricles. Capillaries and veins carry blood later in its route, while atria are heart chambers, not vessels.
