inflammation

Definition
a series of dynamic processes by which tissues respond to injury.

acute inflammation: involves vascular
chronic inflammation: connective tissues
Term

 

classical signs of acute inflammation

Definition
calor-heat
rubor-color
tumor-swelling
dolor-pain
functio laesa
Term

 

acute inflammation

 

tissue events

Definition
hyperemia- large amounts of blood
exudation
emigration of leukocytes
Term

 

hyperemia

Definition
tissue injury-cell damage-release of chemical mediatiors (histamine) then vascular dilation-hyperemia and
vascular damage-leakage
Term

 

effects of histamine

Definition
vasodialation/permeability

leakage of:
fluid
protein
more fluid
Term

 

exudates

 

Definition
hyperemia and vascular damage-protein loss from capillaries-low plasma oncotic pressure-fluid leakage-exudation (fluid shift)-edema
Term

 

exudates

Definition
non-cellular
-serous (low protein, blister)
-fibrinous(sticky, thick)
cellular
-purulent (pus, infection)
-suppurative
mixed
Term

 

emigration of leukocyyes

Definition
fluid exudation-increased blood viscosity-sluggish blood flow-leukocyte margination and pavementing-emigration of leukocytes-chemotactic factors
Term

 

inflammatory diseases

Definition
coronary artery disease
ARDS
asthma
pneumonia
glomerulonephritis
inflammatory dieases of the colon
liver cirrhosis
Term

 

acute inflammation

consequences

Definition
resolution: resoration of function
suppuration: pussing with WBC
-abscesses, fustulas, calcification
repair: tissue of origin
organization: scar, granulomas
chronicity: chronic inflammation
Term

 

abcess

Definition
infected, puss filled place on the body
Term

 

fistula

Definition
narrow passage or duct formed by disease or injury, as one leading from an abcess to a free surface or from one cavity to another

wound healing

-planned surgical incision-little to no scar tissue
healing by second intention (secondary union)
-tissue loss: trauma, necrosis
