c. phagocytosis is the process of engulfing the particle or bacteria and digest it.
steps of phagocytosis:
step 1; the cell that perform phagocytosis is activated.immune cells activates ,when the cells are near bacterial cells..
step2:movement of phagocyte toward a concentrationof molecules.immune cells picks chemical signas and moves towards.
step4 3: the cell that attached to cell itwill ingest
step4:cell ingests the particle ,which is enclosed in vesicle(phagosome)
step5: a lysosome fuses with phagosome.phagosome fused with lysosome is called a phagolysosome.
step6:cellular waste. broken down the molecules which are not used,is exocytosis.

d.one way a pathogen could escape pagocytosis is pathogens may invade or remain confined to regions inaccessible to phagocytes.eg;urinary bladder,broken skin.
another way is avoiding provoking inflammatory response,withoutinflammation pathogens will not attract the phagocytes.
