Immune Flashcards
STOP INFECTION
- WAY: WASH YOUR HANDS
INTACT SKIN IS FIRSTLINE DEFENSE
Tears, mucous, saliva are 1stline and innate
ANTIGEN
-SUBSTANCE THAT CAN ELICIT IMMUNE RESPONSE
-CAN MARK CELLS AS SELF OR NON-SELF
-CAN STIMULATE B LYMPHOCYTES AND CYTOTOXIC RESPONSES
AUTOANTIGENS-ON BODY’S OWN CELLS/ALL OTHERS ARE FOREIGN
INFLAMMATION HAPPENS WHEN NEUTROPHILS, MONOCYTES AND MACROPHAGES ENCOUNTER ANTIGEN
INNATE IMMUNITY
“BORN WITH”
INCLUDE SKIN, CHEMICALS, SOME IMMUNE SYSTEM CELLS, TEARS (FIRST-LINE DEFENSES)
NON-SPECIFIC DEFENSES (Protects against all potential pathogens)
IMMEDIATE OR WITHIN HOURS AFTER ANTIGEN PRESENTATION
ACQUIRED IMMUNITY
IMMUNITY ONE IS NOT BORN WITH, BUT ACQUIRED AFTER BIRTH AT SOME POINT
PASSIVE IMMUNITY
ACQUISITION OF IMMUNITY PASSIVELY
EXAMPLES:
ACQUISITION OF IGA FROM MOTHER IN HIGH CONCENTRATION), MOM CAN PASS FLU ANTIBODIES (PLACENTA AND BREAST MILK)
MONOCLONAL ANTIBODY ADMINISTRATION
IGG INJECTION (IMMUNOGLOBULIN INJECTION)
ACTIVE IMMUNITY
AFTER INTRODUCTION OF PATHOGEN, BODY FORMS DEFENSE
EX: VACCINES CAUSES IT (THE RESPONSE)
EX: ILLNESS/INFECTION CAUSES IT (THE RESPONSE)
LYMPHOCYTES ARE ASSOCIATED WITH THE CREATION AND MAINTENANCE OF THE DEFENSE (B CELLS AND T CELLS)
ARTIFICIAL (VACCINATION)
NATURAL (INFECTION)
ADAPTIVE IMMUNITY
MMUNITY THAT OCCURS, BECAUSE THE BODY NEEDS TO MAKE IT HAPPEN TO REMAIN HEALTHY
ANTIBODIES ARE A PART OF THIS
SPECIFIC IMMUNITY
IMMUNITY AGAINST A SPECIFIC DISEASE OR ANTIGEN
THIS INVOLVES THE BODY “BUILDING” AN “ARMY,” LIKE SPECIFIC B CELLS
HOW DO IMMUNIZATIONS WORK
BODY IS GIVEN (IM, NASAL, ETC…) ANTIGEN (LIVE OR NOT)
OFTEN A PIECE OF THE VIRUS/BACTERIAL INFO IS IN THE IMMUNIZATION
BODY RESPONDS FIRST WITH NON-SPECIFIC IMMUNITY, THEN BUILDS AN ARMY FOR THE NEXT TIME IT SEES THIS PARTICULAR ANTIGEN
IMMUNE RESPONSE
THE REACTION OF THE CELLS AND FLUIDS OF THE BODY TO THE PRESENCE OF A SUBSTANCE WHICH IS NOT RECOGNIZED AS A CONSTITUENT OF THE BODY ITSELF.
INFLAMMATORY RESPONSE
RESPONSE OF THE BODY TO DISEASE OR INJURY RESULTING IN PAIN, HEAT, REDNESS AND SWELLING.
The inflammatory response is innate
DEFINE INFLAMMATION
A LOCALIZED PHYSICAL CONDITION IN WHICH PART OF THE BODY BECOMES REDDENED, SWOLLEN, HOT, AND OFTEN PAINFUL, ESPECIALLY AS A REACTION TO INJURY OR INFECTION.
CARDINAL SIGNS OF INFLAMMATION
REDNESS (FROM INCREASED BLOOD FLOW)-PLEASE NOTE LOCAL HEAT WITH LOCALIZED INFLAMMATION AND FEVER WITH SYSTEMIC INFLAMMATION
HEAT/WARMTH (FROM INCREASED BLOOD FLOW)
SWELLING (MOVEMENT OF FLUID AND COMPONENTS INTO TISSUE AFTER INCREASED CAPILLARY PERMEABILITY)
PAIN (FROM PRESSURE FROM THE SWELLING AND CHEMICAL MEDIATORS)
POSSIBLE LOSS OF FUNCTION (FROM SWELLING)
they allow more blood flow
EDEMA
A CONDITION CHARACTERIZED BY AN EXCESS OF WATERY FLUID COLLECTING IN THE CAVITIES OR TISSUES OF THE BODY
SYSTEMIC INFLAMMATION
FEVER
OVERALL BODY ACHES
LOCALIZED INFLAMMATION
CARDINAL SIGNS AT SITE
LEUKOCYTES
WHITE BLOOD CELLS
MACROPHAGES
A LARGE PHAGOCYTIC CELL FOUND IN STATIONARY FORM IN THE TISSUES OR AS A MOBILE WHITE BLOOD CELL, ESPECIALLY AT SITES OF INFECTION/INFLAMMATION
MATURED MONOCYTE
MIGRATES INTO TISSUES FROM THE BLOOD
CAN ENGULF FOREIGN ANTIGENS
PHAGOCYTIC, ALSO INVOLVED IN “SIGNALING”
EXISTS WITHIN THE TISSUES AND WAS PRODUCED BY MONOCYTE DIFFERENTIATION
RELEASE PYROGENS (THESE CAN REGULATE TEMPERATURE)
BASOPHILS
SOME OF THESE, WHEN FOUND IN CONNECTIVE TISSUE, ARE CALLED MAST CELLS (ONCE THERE, THEY DON’T GO BACK
WOULD BE FOUND IN HIGH CONCENTRATION IN BLOOD OF A CLIENT EXPERIENCEING A SEVERE ALLERGIC REACTION
