White blood cell. Coloured transmission electron micrograph (TEM) of an eosinophil (a type of white blood cell), part of the body's immune system. The cell's nucleus (green) contains chromatin (yellow). In the cell's cytoplasm (light brown) are many enzyme-containing granules (dark brown), used to destroy invading organisms. Eosinophils are found in many connective tissues. They are involved in the body's allergic response and help to defend the body from invading parasites.
