Verified step by step guidance

Understand the concept of atherosclerosis: Atherosclerosis is a condition where plaque builds up inside the arteries, leading to reduced blood flow. It primarily affects arteries rather than veins or capillaries due to the high pressure and turbulent blood flow in arteries.

Review the function of coronary arteries: Coronary arteries supply oxygen-rich blood to the heart muscle. They are critical for maintaining heart function and are prone to atherosclerosis due to their small diameter and the high demand for oxygenated blood.

Compare the susceptibility of capillaries: Capillaries are tiny blood vessels where gas and nutrient exchange occurs. They are not prone to atherosclerosis because they do not experience high pressure or turbulent blood flow like arteries do.

Evaluate pulmonary veins: Pulmonary veins carry oxygenated blood from the lungs to the heart. Veins are generally less susceptible to atherosclerosis because they operate under lower pressure compared to arteries.

Analyze the inferior vena cava: The inferior vena cava is a large vein that carries deoxygenated blood from the lower body to the heart. Like other veins, it is not prone to atherosclerosis due to the lower pressure and absence of turbulent flow.
