select all that apply for third line of defense

• specific

• stimulates production of antibodies

• happens after exposure to a pathogen

• involves interferons

define inflammation

• serves as a warning sign

• a nonspecific bodily defense used to localize and rid of an agent

• goes hand in hand with infection

• characterized by edema, erythema, warmth, pain, and possible LOF

what is ischemia?

• characterized by edema and erythema

• can result in tissue necrosis

• indicative of infection

• inadequate blood flow to tissues

define infarction

• micro-organisms are present at the site

• due to obstructed blood flow or inadequate blood supply

• a nonspecific response to a pathogen

• injury or death of tissue

define hyperemia

• increased blood flow to area, results in an excess pooling of blood

• a chemical mediator that triggers inflammation

• presents itself as pain, edema, and erythema

• decreased blood flow and tissue death

select all LOCAl effects of inflammation

• loss of function and pain

• redness and warmth

• edema and drainage

• malaise

Select all SYSTEMIC effects of inflammation

• pyrexia

• malasie, fatigue

• emesis and nausea

• pain

select complications of inflammation

• local complications such as joint stiffness and pain

• skeletal muscle spasms

• infection as inflammed tissue is easier to penetrate

• additional pain and pressure
