Macrophages circulate through the blood, searching for bacterial infection. When bacteria are found, macrophages engulf and digest them. This series of three paintings shows a macrophage engulfing a bacterium. Only a portion of the two cells, where a pseudopod of the macrophage is extending over the bacterium, is shown. The original paintings are 1 meter tall--at this magnification, the macrophage would fill most of a building.
