Phagocytosis
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Phagocytosis is the endocytosis variant in which a cell engulfs a large particle, extending its membrane around the target before enclosing it.
Show
A neutrophil phagocytizes an invading microorganism and destroys it after the resulting vesicle fuses with a lysosome.
Watch for
Phagocytosis engulfs particulate matter specifically — taking in surrounding fluid is a separate process, covered next.
