CHAPTER 15 ( INTRODUCTION TO THE IMMUNE RESPONSE AND INFLAMMATION ) Flashcards
Foreign Proteim
Antigen
released from INJURED CELLS to stimulate the inflammatory response THROUGH ACTIVATION OF various chemical substances.
ARACHIDONIC ACID
A disorder that OCCURS WHEN THE BODY RESPONDS TO SPECIFIC SELF- ANTIGENS “ TO PRODUCE ANTIBODIES OR CELL- MEDIATED RESPONSES against its own cells
AUTOIMMUNE DISEASE
What are the “ BODY DEFENSES “?
B C C T
- Barrier Defenses
- Cellular Defenses
- The Inflammatory Response
- The Immune Response
Barrier Defenses includes
- Skin
- Mucuous membranes
- Gastric Acid
- MHC ( Major Histocompatibility Complex )
It is the” FIRST LINE OF DEFENSE” and Act as a physical barrier to “PROTECT THE INTERNAL TISSUES AND ORGANS OF THE BODY”
SKIN
It is the areas of the body that are EXPOSED TO EXTERNAL INFLUENCES but DO NOT HAVE BENEFIT OF SKIN PROTECTION.
Mucuos Membranes
Also act as “ Physical Barrier” to Invasion
Mucuous membranes
In the conducting airways of the respiratory tract, the mucuos membrane is line with “TINY, HAIR-LIKE PROCESSES CALLED?
Cilia
What “CILIA” DO?
The cilia “ SWEEP ANY CAPTURE PATHOGENS OR FOREIGN MATERIALS UPWARD TOWARD THE MOUTH , WHERE THEY WILL BE SWALLOWED. THE CILIA ALSO CAN MOVE THE CAPTURED MATERIAL TO AN AREA CAUSING IRRITATION, WHIXH LEADS TO REMOVAL BY “COUGHING” OR “SNEEZING”
What does mucous membrade do in “GI Tract”?
It serves as a protective coating, preventung EROSION of GI cells by the “ acidic environment of the stomach” ,
The acidity of the stomach not only “AIDS DIGESTION BUT ALSO DESTROYS MANY WOULD- BE PATHOGENS.
Normal Flora that live in this acidix environment also help to destroy many of these ingested pathogens.
The body’s last barrier of defense is the ability to “ DISTINGUISH BETWEEN SELF - CELLS AND FOREIGN CELLS”
MHC ( Major Histocompatibility Complex )
The MHC produces several proteins called?
HISTOCOMPATIBILITY ANTIGENS / HUMAB LEUKOCYTE ANTIGENS ( HLAs )
Where antigens ( protein ) are located?
LOCATED ON THE CELL MEMBRANE
Where antigens ( protein ) are located?
LOCATED ON THE CELL MEMBRANE
Cells that do not have “proteins” are identified as ?
FOREIGN ( targeted for destriuction by the body )
Any foreign pathogen that manages to Get past the barrier defenses will encounter the
HUMAN INFLAMMATORY AND IMMUNE SYSTEMS / MONONUCLEAR PHAGOCYTE SYSTEM ( MPS )
The MPS ( Mononuclear Phagocyte System ) is composed Primarilg of ??
LEUKOCYTES, LYMPHOCYTES, LYMPHOID TISSUES, AND NUMEROUS CHEMICAL MEDIATORS.
Stem cells in the “ bone marrow “ produce two types of WBCs or Leukocytes. What is these two?
LYMPHOCYTES & MYELOCYTES
The _______ are the “ KEY COMPONENTS OF THE IMMUNE SYSTEM “ and consist of T Cells & B Cells, and natural killer cells.
LYMPHOCYTES
The Myelocytes include??
- Neutrophils
- Basophils
- Eosinophils
- Monocytes / Macrophages
It is the “ KEY COMPONENTS OF THE IMMUNE SYSTEM “
Lymphocytes
Basis of the two types of cells: Lymphocytes and Myelocytes ( LM )
LEUKOCYTES
● THE BODY HAS SEVERAL DEFENSE MECHANISMS IN PLACE TO PROTECT IT FROM INJURY OR FOREIGN INVASION
True
BARRIES DEFENSES INCLUDES:
A. Skin
B. Mucuous membranes
C. Normal Flora
D. Gastric Acid
It is the “ Local Reaction “ of the body to “ invasion “ or “ injury “
The Inflammatory Response
______ causes the activation of a chemical in plasma called “ Factor XII or Hageman Factor.
CELL INJURY
______is responsible for “ ACTIVATING AT LEAST THREE SYSTEMS IN THE BODY
HAGEMAN FACTOR
Also known as Factor XII
Hageman factor
Also known as Factor XII
Hageman factor
The Hageman Factor is responsible for activating at least which 3 systems in the body ?
- Kinin System
- Clotting Cascade
- Plasminogen System
Initiates “ blood clotting “
CLOTTING CASCADE
