Atherosclerosis: How Plaque Buildup Narrows Arteries and Impacts Blood Flow #3313876 (License: Personal Use)

This medical illustration depicts two cross-sections of arteries: the upper vessel exhibits significant atherosclerotic plaque-a yellow, lipid-rich deposit-bulging into the lumen and restricting blood flow; the lower vessel is healthy, with smooth endothelium and unimpeded circulation of red blood cells, platelets, and leukocytes. The contrast highlights how chronic inflammation and cholesterol deposition lead to arterial stiffening and increased risk of thrombosis or ischemia.

Used in cardiology, patient education, and health websites to explain coronary artery disease, stroke risk, and preventive care; matches user intent for understanding symptoms, causes, and treatment of vascular disease.
