approximately 1013 human cells and 1014 bacterial‚ protozoan and fungal cells (Immunity‚ 2007). To defense against those pathogens‚ our body generate three levels of defense: (1) anatomic barriers; (2) innate immune system and (3) adaptive immune system. The first level of defense involves the inhibition effects of skin‚ mucus secretion of the respiratory tract‚ low pH of stomach‚ etc. If pathogens do get through the physiological barrier‚ the innate and adaptive immune system come into play. Innate immunity

TASK 1 The body ’s first line of defence against pathogens uses mostly physical and chemical barriers such as sweat‚ skin‚ tears‚ mucus‚ stomach acid‚ and so on.

Mucus can trap pathogens‚ which are then washed away or destroyed by chemicals. Tears‚ sweat‚ and saliva have certain chemicals which can kill different pathogens. Bacterial spores and fungi are naturally present
