“Y” shape so that it can connect and transfer chemicals to pathogen

Question 7

What is non specific defence mechanisms?

Answer 7

Non specific fend off all microorganism equally

Question 8

What is specific defence mechanisms?

Answer 8

Mechanisms that are tailored to kill particular cells and pathogens in the body

Question 9

What are cytokins?

Answer 9

Small proteins which control the growth of immune system cells & blood cells, when released it signals the immune system to do it’s job

Question 10

What is the innate immune response?

Answer 10

white blood cells that resist any foreign substance, lacks memory

Question 11

What is the adaptive immune response?

Answer 11

white blood cells with a memory, knows how to respond to pathogen if it comes back

Question 12

What are physical barriers?

Answer 12

host’s first line of defence when a pathogen enters the body

Question 13

What happens if pathogen passes physical barriers?

Answer 13

They encounter innate cells which are the 2nd line of defence

Question 14

Question 21

Answer 23

communication and collaboration, development, influence, application and limitation

Question 24

What type of molecule are antibodies.

Answer 24

proteins

Question 25

What is phagocytosis

Answer 25

The process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria)

Question 26

How does the body tell the difference between self and non self cells?

Answer 26

leukocyte antigens

Question 27

Difference between antibodies and antigens

Answer 27

Antigen = bad microorganism
Antibodies = fight off bad things

Question 28

passive vs active

Answer 28

passive = antibodies spread from something else (person)
Active = antibodies created by themselves
