Artery

A generic muscular artery shown as a short tubular blood vessel segment, cutaway, or circular cross-section. It has an outer surface and a thick, sturdy wall with clear concentric layers: a thin smooth inner endothelial lining, a broad prominent smooth-muscle middle layer with elastic character, and an outer connective tissue layer. The central lumen is round to slightly oval and generally narrower relative to the wall thickness, though it may appear moderately wide in some cross-sectional depictions. Overall it has a strong, resilient, clean anatomical or clipart-style appearance representing an oxygenated systemic blood vessel.
