#1
Front (Question)

susceptibility

Back (Answer)

lack of resistance to a disease

#2
Front (Question)

immunity

Back (Answer)

ability to ward off disease

#3
Front (Question)

innate immunity

Back (Answer)

defences against any pathogen

#4
Front (Question)

adaptive immunity

Back (Answer)

adaptive resistance to a specific pathogen

#5
Front (Question)

facts about innate immunity

Back (Answer)

• nonspecific defence mechanism • provides immediate defence against infection • come into play immediately • include physical barriers ( skin, proteins in blood and immune cells)

#6
Front (Question)

inflammation

Back (Answer)

• first response of the immune system to infection • stimulated by chemical factors released by injured cells

#7
Front (Question)

whats PRR

Back (Answer)

Pattern recognition receptors

#8
Front (Question)

whats PAMP

Back (Answer)

Pathogen associated molecular patterns

#9
Front (Question)

inflammation signs

Back (Answer)

redness swelling heat pain mucus

#10
Front (Question)

what inflammatory mediators do cells release

Back (Answer)

histamine serotonin prostaglandins bradykinin leukotrienes

#11
Front (Question)

what are toll like receptors and example

Back (Answer)

Toll-like receptors (TLRs) are germline-encoded pattern recognition receptors • RNA/DNA virus • gram positive/negative • fungi / protists

#12
Front (Question)

where are toll like receptors found

Back (Answer)

macrophages mast cells dendritic cells

#13
Front (Question)

what does nod stand for

Back (Answer)

Nucleotide-bindingn Oligomerisation Domain

#14
Front (Question)

what do Nod-like receptors do

Back (Answer)

sense infection and stress through the recognition of cytoplasmic PAMPs

#15
Front (Question)

other innate immune receptors

Back (Answer)

host anti viral responses - RIG I Like receptors - Cytosolic DNA sensors anti0fungal responses - C type lectin receptors

#16
Front (Question)

cells of the innate immune response

Back (Answer)

phagocytes neutrophil dendritic cells mast cells basophils eosinophils natural killer cells t-cells

#17
Front (Question)

whats the complement system

Back (Answer)

the ability of antibodies and phagocytic cells to clear pathogens from an organism

#18
Front (Question)

what immunity is only found in vertebrates

Back (Answer)

adaptive immunity

#19
Front (Question)

what are antigens

Back (Answer)

substances that can evoke a response from a B or T cell

#20
Front (Question)

whats the small accessible part of an antigen that binds to an antigen called

Back (Answer)

epitope

#21
Front (Question)

antigens example

Back (Answer)

intracellular antigens extracellular antigens dendritic cells lymph nodes

#22
Front (Question)

adaptive immune cells

Back (Answer)

B,T,Natural killer cells antibodies

#23
Front (Question)

where does T-cell mature where does B-cell mature

Back (Answer)

thymus spleen and SLO ( secondary lymphoid organs)

#24
Front (Question)

antibody function

Back (Answer)

do not kill pathogens they mark pathogens for destruction neutralisation
