#1
Front (Question)

What is the immune system?

Back (Answer)

Anything that protects an organism from an invader

#2
Front (Question)

Innate immunity

Back (Answer)

First and Second line of defence against pathogens Fast and non specific No memory

#3
Front (Question)

is innate immunity specific?

Back (Answer)

Nope

#4
Front (Question)

Which parts of the body are the first line of defence

Back (Answer)

• Skin • Mucus membrane • Normal microbiota

#5
Front (Question)

Which things are part of the 2nd line of defence

Back (Answer)

• Innate immune cells • Inflammation

#6
Front (Question)

Adaptive Immunity

Back (Answer)

The third line of defence - Takes time to activate - Targets specific pathogens - Generates memory

#7
Front (Question)

Which mechanisms are part of the third line of defence?

Back (Answer)

• Specialized immune cells • Antibodies

#8
Front (Question)

Where do most immune cells originally come from

Back (Answer)

The bones

#9
Front (Question)

Which cells are part of the innate immune system

Back (Answer)

-Macrophages -Eosinophil -Monocyte -Neutrophil -Dendritic Cells

#10
Front (Question)

Which cells are part of the adaptive immune system

Back (Answer)

• T-lymphatocyte • B-lymphatocyte • Dendritic cells

#11
Front (Question)

Function of neutrophil

Back (Answer)

Both a phagocyte and granulocyte • Reinforcements responding to cytokines • Ingest pathogens and release enzymes to kill them (degranulation)

#12
Front (Question)

Function of a macrophage

Back (Answer)

(Phagocyte) 1st response - eats invader and calls for reinforcements - Displays antigens to activate other immune cells - release cytokines (smell) to call neutrophils

#13
Front (Question)

Function of dendritic cells

Back (Answer)

(Phagocyte) - Grabs antigens and presents them to B and T cell in the lymph node - eats antigens

#14
Front (Question)

Phagocyte

Back (Answer)

Eats stuff

#15
Front (Question)

Granulocyte

Back (Answer)

Shoots a granule to kill

#16
Front (Question)

Does bacteria come in contact with the cytoplasm in phagocytosis

Back (Answer)

No

#17
Front (Question)

What are the 2 outcomes of a pathogen invasion

Back (Answer)

• Pathogen elimination • Pathogen takes over

#18
Front (Question)

Antigen

Back (Answer)

Any substance that causes the body to make an immune response

#19
Front (Question)

What displays viral antigens

Back (Answer)

MHC I

#20
Front (Question)

What displays bacterial antigens

Back (Answer)

MHC II

#21
Front (Question)

Function of B-cells

Back (Answer)

Make antibodies - If arms are attached to the cell, it’s a receptor - if it leaves the cell body, its an antibody

#22
Front (Question)

What are the two main types of T-cell

Back (Answer)

Unactivated t-cell Cytotoxic t-cell

#23
Front (Question)

Naive t-cell

Back (Answer)

Unactivated t-cell

#24
Front (Question)

Activated t-cell

Back (Answer)

Cytotoxic t-cell
