The process by which cells engulf solid matter is called phagocytosis. There are four essential steps in phagocytosis:
(1) the plasma membrane entraps the food particle, (2) a vacuole forms within the cell to contain the food particle,
(3) lysosomes fuse with the food vacuole, and
(4) enzymes of the lysosomes digest the food particle.

Phagocytosis: The process by which a cell engulfs particles such as bacteria, other microorganisms, aged red blood cells, foreign matter, etc. The principal phagocytes include the neutrophils and monocytes (types of white blood cells).
The prefix "phago-" comes from the Greek "phago" meaning "to eat."
