Artery. Coloured scanning electron micrograph (SEM) of a sectioned artery containing red blood cells (erythrocytes, red). Arteries carry oxygenated blood to the body's tissues. They typically have a thick wall (blue/green) to cope with the high pressure of the blood being pumped around the body by the beating heart. Magnification unknown.
