This 3-D image was created by Gary Carlson to illustrate the process of phagocytosis.

Phagocytosis is a process where a cell incorporates a particle by extending pseudopodia and drawing the particle into a vacuole of its cytoplasm.

In the artwork, the macrophage uses pseudopodia to engage pathogenic bacteria.
