Antigens and phagocytosis

Cards (16)

Defense mechanisms ?
antibodies, phagocytes and lymphocytes, skin, mucus, stomach acid, tears, inflammation
Examples of surface proteins ?
pathogenic cells, abnormal body cells, toxins
Where are antigens found? 
cell surface membranes, bacterial cell walls
Phagocytes ?
type of WBC in the bone marrow
Phagocytosis ?
Recognising and engulfing pathogens
Is phagocytosis a non specific or specific immune response?
non specific
Each antigen has its own unique ... ?
...shape
Self antigens ?
your own antigens
non self antigens?
antigensnot produced by the own body that trigger an immune response
Where are phagocytes made?
bone marrow
types of phagocytes?
neutrophils, macrophages
neutrophils ?
engulf and digest pathogens
macrophages ?
punch holes on the bacteria to make them more appealing for neutrophils to destroy
non specific immune response?
the immediate response to pathogens
Specific defense response?
third line of defense against pathogens
process of phagocytosis?
pathogen recognised as foreign, attaches to phagocyte by surface receptors, pathogen engulfed by phagocyte and becomes phagosome (endocytosis), lysosomes fuse and release enzymes, waste removed (exocytosis)
