What occurs to blood vessels in arteriosclerosis?

In arteriosclerosis, blood vessels lose elasticity, which is a fundamental characteristic of this condition. This loss of elasticity is due to the thickening and hardening of the arterial walls, often caused by plaque buildup, which comprises fats, cholesterol, and other substances. As the artery walls become stiffer, they are less able to stretch and accommodate the pulsatile flow of blood from the heart. This can lead to increased blood pressure and a higher risk of cardiovascular events such as heart attacks or strokes.

Understanding this change in the vascular structure is crucial, as it explains the pathophysiology of arteriosclerosis and its impact on overall cardiovascular health. In contrast, flexibility in blood vessels is associated with healthier arteries, allowing them to effectively manage blood flow and pressure.
