Anatomy of a Healthy Artery - Blood Vessel Structure Diagram #3224423 (License: Personal Use)

This diagram depicts a normal, non-atherosclerotic artery in cross-section, featuring a smooth endothelial lining (tunica intima), a muscular middle layer (tunica media), and an outer connective tissue layer (tunica externa). The central lumen remains wide and unobstructed, allowing efficient blood circulation. The wavy outer contour reflects natural vessel elasticity.

Used in medical education, patient brochures, and cardiovascular health websites to illustrate normal vascular anatomy; supports user intent to understand heart disease prevention or basic circulatory physiology.
