Arteriosclerosis refers to the thickening and hardening of the arterial walls, which can lead to loss of elasticity and narrowed arteries. This condition is significant because it can restrict blood flow and increase the risk of cardiovascular problems, such as heart attacks and strokes. The hardening of the arteries is primarily due to the buildup of plaque, which consists of fats, cholesterol, and other substances. Understanding arteriosclerosis is crucial in both prevention and management of cardiovascular health, as it highlights the importance of maintaining a healthy lifestyle to keep arteries flexible and functioning properly.
