How Cholesterol Causes Artery Narrowing - Visual Guide #3313860 (License: Personal Use)

The image illustrates four progressive stages of arterial atherosclerosis: a normal healthy artery, early yellow cholesterol plaque formation on vessel walls, increased plaque accumulation constricting the lumen, and finally a severely narrowed artery with restricted blood flow. Each stage is connected by arrows to emphasize the chronic, cumulative nature of the condition.

Used in health education articles, cardiology patient resources, or preventive medicine guides to explain atherosclerosis and cardiovascular risk; matches user intent to understand how high cholesterol leads to heart disease.
