Q

Lines of defence

A

1- physical barrier

2- non specific response

3- immune response

17
Q

Physical barrier

A

Skin : protects bony from microscopic organisms

Mucous: contains antibody imnogobline that stops pathogens

Cilia: little hairs

18
Q

Non specific response

A

Inflammatory response :

Puss: white blood cells distort pathogen, the dead cells are puss

19
Q

Immune response

A

1

20
Q

Passive immunity

A

When you inoculate body with antibodies that fight antigens

21
Q

Active immunity

A

Vaccinating with a dead or weakened or related form of disease. This stimulates immune response without getting it

22
Q

Natural immunity

A

Once you have had a disease your body recognises the antigen

23
Q

Artificial immunity

A

When you stimulate immune response to fight antigen without it falling by exposing body to pathogen in small quantities

24
Q

Disease

A

A disorder that effects a particular part of the body , and is not caused by physical activity
