Blood-filled artery. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a foetal aorta filled with red blood cells (erythrocytes, red). The aorta is the main body artery and the largest in the body. Arteries carry oxygenated blood to the body's tissues. They typically have a thick wall (pink) to cope with the high pressure of the blood being pumped around the body by the heart. Magnification unknown.
