About this image

Coloured scanning electron micrograph showing red and white blood cells inside a small blood vessel. The sample was prepared by freeze fracturing, rapidly freezing the sample with liquid nitrogen such that tissues are instantly preserved. If the sample is broken, the inner structures are revealed. In this frame, a tiny vein, or venule, has been opened to show the blood cells inside. This image was created in monochrome and later digitally colourised. Bedford, Bedfordshire, United Kingdom
