Phagocytosis
Captions available
The idea
Phagocytosis is the endocytosis variant in which a cell engulfs a large particle, extending its membrane around the target before enclosing it.
In practice
A neutrophil phagocytizes an invading microorganism and destroys it after the resulting vesicle fuses with a lysosome.
Where people slip
Phagocytosis engulfs particulate matter specifically — taking in surrounding fluid is a separate process, covered next.
