Arteries at which sites are more common for atheroma formation?

Atheroma formation, which is the buildup of fatty plaques within the arterial walls, tends to occur at specific locations in the arterial system due to various hemodynamic and structural factors. The correct answer points to areas such as bifurcations, coronaries, and carotids, which are particularly susceptible to developing atheromas.

Bifurcations are points in the arterial tree where blood vessels split into two branches. These sites experience disturbed flow dynamics, which can contribute to endothelial injury and facilitate the accumulation of lipids, inflammatory cells, and other factors that lead to plaque formation. The carotid arteries, which supply blood to the brain, and the coronary arteries, supplying the heart muscle, are common sites for atheroma development due to their anatomical structure and physiological demands. The turbulence and varying shear stresses at these regions heighten risk factors associated with atherosclerosis.

In contrast, capillary beds and arterioles, while crucial for microcirculation, do not experience the same shear stresses conducive to atheroma formation as larger arteries do. Furthermore, veins and venules do not typically develop atherosclerotic plaques in the same manner as arteries due to differences in pressure and flow dynamics. While the aorta can form a
