Phagocytosis Flashcards
What are phagocytes?
White blood cells
What do phagocytes do’
Engulf pathogens
What do lymphocytes do?
Produce antibodies
What are lymphocytes used for?
Long term immunity
What are antigens?
Molecules that sit on the cell membrane
What attrats/friggersphagocytosis?
High concentration of toxins
What happens when the-phagocytes reach the pathogen?
They attach to the antigens which are complimentary
1st stage of phagocytosis
Endocytosis-engulfing of microbe
Where does the pathogen get engulfed into?
Vessicle-phagosome
2nd stage
Fusion of phase some and lysosome = phagolysosone
3rd stage
Killing and digestion = enzymes in lysosome break down (partially)
What else does the lysosomes do to the pathogen?
Keeps it’s antigens
What does it do with the antigens?
Puts it on to the surface of phagocyte
4th stage
Exocytosis: removal anything not needed
