10 Questions
Which cells are responsible for ingesting and destroying microbes?
Neutrophils and macrophages
What is the size range of particles that can be ingested through phagocytosis?
Between 0.5 μm and 1 μm in diameter
What is the first step of phagocytosis?
Chemotaxis
What happens to the pathogen after it is engulfed by the phagocyte?
It is placed inside a vesicle called the phagosome
What is the final step of phagocytosis?
Digestion/breakdown of the pathogen
Which cells are capable of phagocytosis?
Neutrophils and macrophages
What is the size range of particles that can be ingested through phagocytosis?
Greater than 0.5 μm in diameter
What is the purpose of chemotaxis in phagocytosis?
To guide the phagocyte towards the sites of infection
What happens when the phagosome fuses with a lysosome?
A phagolysosome is formed
What is the purpose of residual body formation in phagocytosis?
To remove indigestible particles
