inflammation
what are the factors involved in protective responses and bodily repair?
- inflammatory reaction
- immune response
- tissue repair and wound healing
The causes of inflammation are immune responses to
infectious microorganisms, trauma, surgery, caustic chemicals, extremes hots and colds, ischemic damage to body tissues,.
What is seen after an injury as part of the defense system of the body?
inflammatory response
inflammatory response is to prevent _

false. prolonged or excess inflammation can be harmful
The inflammatory response causes _______
increase in blood flow and vasodilation
What are the vascular changes that happen with inflammation?
- an immediate transient response
- an immediate sustained response
- a delayed hemodynamic response
A immediate transient vascular response occurs with
minor injury
An immediate sustained vascular response occurs with
more serious injuries and continues for several days and damages the vessels in the area
A delayed hemodynamic vascular response involves
an increase in capillary permeability that occurs 4 to 24 hours after injury
What are the big fighters of inflammation?
neurophils
cellular stage of acute inflammation is marked by the movement of
phagocytic white blood cells into the area
What kind of inflammation: short duration, non-specific, fix the problem. remove injurious agents and limit tissue damage. last 48-72 hours
acute inflammation
What kind of inflammation: longer duration, pokes on immune system, fails to evoke an acute response. Bad responses
chronic inflammation
Prominet systemic manifestations of inflammation:
acute phase response, alterations in white blood cell count, fever, sepsis and septic shock
What is the most common thing to see in labs of inflammation?
WBC is elevated
What could a quick elevation in WBC mean?
An acute inflammation response trying to combat what has happened
Wounds don’t heal well with what
edema
Causes of impaired wound healing:
malnutrition, impaired blood flow, infection, wound separation, foreign body, age
