Detailed explanation-1: -The walls of veins have the same three layers as the arteries. 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.
Detailed explanation-2: -An aortic aneurysm is a bulge or ballooning-out in the wall of the aorta, the main artery that runs from your heart through your chest and abdomen. An aneurysm can become life-threatening if the artery walls split-called a dissection-or the aneurysm ruptures, both of which can cause uncontrolled bleeding.
Detailed explanation-3: -At each body part, a network of tiny blood vessels called capillaries connects the very small artery branches to very small veins. The capillaries have very thin walls, and through them, nutrients and oxygen are delivered to the cells. Waste products are brought into the capillaries.
