Artery

Generic anatomical illustration of an artery as a short red to pink-red cylindrical blood vessel segment, shown in cross-section, cutaway, or partial side view. The vessel has a smooth outer contour, clean circular to slightly oval cut end, and a prominently thick, sturdy wall that is clearly more muscular and elastic than a vein. The wall may show layered structure, including a thin smooth pale inner lining, a prominent pink-red muscular middle layer, and a slightly paler outer layer. The central lumen is round to slightly oval and relatively narrow to moderate in size compared with the wall thickness. Overall appearance is firm, elastic, high-pressure, and rendered in a simple medical diagram or anatomical clipart style.
