PATHOLOGY

Detailed explanation-1: -Blood vessels include arteries, capillaries, and veins. Arteries carry blood away from the heart and can divide into large and small arteries. Large arteries receive the highest pressure of blood flow and are thicker and more elastic to accommodate the high pressures.

Detailed explanation-2: -The aorta has high-pressure, oxygenated blood pumped directly into it from the left ventricle of the heart.

Detailed explanation-3: -Pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure.
