Always a part of you

Most living things are made up of one or more cells. These are more cells from our bodies and from plants.

Macrophage Macrophage means "big eater". Macrophages are white blood cells that crawl around in the extracellular fluids of your body and gobble up microbes and other foreign material. They ingest these microbes by phagocytosis ("cell eating"). Parts of the cell surround the particle to be eaten, then the macrophage's membrane flows together and the particle ends up inside. In this image, metal particles were eaten, and they are the black spots inside the orange vacuoles. The nucleus is purple, and mitochondria are green.
