SECOND LINE OF DEFENSE INHIBITS INVASION BY: MICROORGANISMS
List the 5 major non specific defenses included in 2nd LINE: Production of anti-microbial proteins, fever, inflammatory response, phagocytosis, & NK cells
NK cells AKA null cells OR natural killer cells
Inflammatory process triggered by: injury to body tissue
Inflammation helps in 3 ways: 1. PREVENT spread of invaders. 2.INITIATE repair mechanism. 3. DISPOSE of cell debries & pathogens.
Four signs of inflammation are: redness, heat, swelling & pain
Fifth POSSIBLE sign of inflammation is: impairment of function
Inflammation begins with release of inflammatory chemicals into: EXTRAcellular fluid from cells
The inflammatory response also includes the release of: blood proteins
Some important inflammatory chemicals are: Compliment sys proteins, Histamines, Kinins, Lymphokines, & prostaglandins (PG)
Inflammatory chemicals promote: VASODILATION
VASODILATION causes HYPEREMIA
HYPEREMIA is: heat and redness
Some chemicals increase permeability of: capillaries
EXUDATE is fluid with proteins (clotting factors)
Pain associated w/inflammation comes from: release of bacterial toxins & pressure from swelling
EDEMA helps 3 ways: 1) ALLOWS ENTRY of clotting proteins 2)BRINGS IN lots of oxygen & nutrients 3) DILATES harmful substances
If the epithelial barrier is breached, what happens: epithelial cells release B-DEFENSINS.
2nd line of defense includes:3 ANTI-MICROBIAL PROTEINS, DEFENSIVE cells & INFLAMMATION
ANTI-MICROBIAL PROTEINS are: chemical weapons
DEFENSIVE CELLS attack: all non self cells
EXUDATE causes: swelling
CHEMO-TACTIC agents are: inflammatory chemicals
B-DEFENSINS are: broad spectrum antibiotics
Prevent-Dispose-Initiate refers to: how inflammation helps
PG is AKA Prostaglandins
Chemical Weapons are: anti-microbial proteins
Inflammatory chemicals are: chemo tactic agents
