3- immune response

Question 17

Physical barrier

Answer 17

Skin : protects bony from microscopic organisms

Mucous: contains antibody imnogobline that stops pathogens

Cilia: little hairs

Question 18

Non specific response

Answer 18

Inflammatory response :

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

Question 19

Immune response

Answer 19

1

Question 20

Answer 20

When you inoculate body with antibodies that fight antigens

Question 21

Active immunity

Answer 21

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

Question 22

Natural immunity

Answer 22

Once you have had a disease your body recognises the antigen

Question 23

Artificial immunity

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

Question 24

Disease

Answer 24

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