PATHOLOGY

Detailed explanation-1: -The pulmonary artery and the aorta, on the other hand, carry blood out of the heart, and therefore carry blood at tremendous pressure owing to the systolic pressure of the ventricles.

Detailed explanation-2: -In the circulatory system, the highest pressure of blood is found to be present at the site of the aorta, while the lowest is found to be within the venous vessels.

Detailed explanation-3: -Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries.
