Define inflammation
The rapid response to tissue damage - injury or infection
10 of 28
What are the four functions of inflammatory exudate (4D)

Serous, Fibrinous, Purulent, Hemorrhagic, Mucoid
12 of 28
What is serous exudate and example
Exuded from blood vessels - blisters
13 of 28
What is fibrinous exudate and example
High in fibrinogen - adhesions following surgery
14 of 28
What is purulent exudate and example
neutrophils and dead inflammatory cells - abscesses
15 of 28
what is hemorrhagic exudate and example
RBCs and fulminating infections
16 of 28
what is mucoid exudate and example
secreated by mucosa - runny nose
17 of 28
what are the 5 causes of inflammation
trauma, thermal injuries, pathogens, immune reactions, foreign material
18 of 28
what are the 7 outcomes of inflammation
resolution, healing, abscess, degeneration, mineralization, necrosis, gagrene
19 of 28
what is resolution
resolves without significant damage to tissue
20 of 28
what is healing
slow regeneration or repair of tissue
21 of 28
what is abscess
persistant accumulation of pus
22 of 28
what is degeneration
the damaged cells degenerate and are not repaired
23 of 28
what is mineralization
calcified deposits are laid down in the soft tissue
24 of 28
what is necrosis
cells die and affected tissue sloughs
25 of 28
what is gangrene
cells die due to lack of blood supply and putrefaction of tissues by anaerobic bacteria
26 of 28
What is acute inflammation
short in duration and once the cause is removed, healing is quick
27 of 28
what are the 3 treatments of acute inflammation
removal of cause, cold compress, NSAID
