Body defence

Post by hoiki426 » Sat Nov 05, 2005 7:50 pm

Actually
Q1~~~what means by"immunity of one pathogen"?
does it mean:
1.) The prossess that our body to produce antibodies to fight pathogen
or 2.) We have memory cells of those pathogen already?

Q2~~~~And I also want to ask

What does "infected by pathogen" mean?
does it mean :
1.) That pathogen has pass thro our barrier and enter our body
or 2.) The pathogen has alreafy damage our body cells , organ ,etc.?

I would say 1 and 1

I never answer questions with answer, I like to give you a clue and let you conclude to have your own answer. So this is my clue:

1. Immunity of one pathogen - it means that the immunity is specific to a certain pathogen. It can be this way because our body has already recognized that pathogen previously. Thus, when there will be re-infection or when the same pathogen come back to infect our body, our defence system knows what the best way it should do to eliminate it, whether by humoral immune response or cell-mediated immune response.

2. Infected by pathogen - The first barrier of our body defence system, that is also the main function of the immune system, is to prevent the pathogens from entering our body. We are so called "healthy" (in physical and clinical term) when our barrier can eliminate this pathogen before come inside and entering our body. We will feel symptom(s) of disease(s) when pathogens are able to break the first barrier and/or start to attack our second barrier or the defence system within our inner environment. We will suffer disease(s) when pathogens are succesfully defeat our barriers and spread out within our body.

So, tell me your answer now ;)
