What “CILIA” DO?

A

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”

● THE BODY HAS SEVERAL DEFENSE MECHANISMS IN PLACE TO PROTECT IT FROM INJURY OR FOREIGN INVASION
True
26
BARRIES DEFENSES INCLUDES:
A. Skin B. Mucuous membranes C. Normal Flora D. Gastric Acid
27
It is the " Local Reaction " of the body to " invasion " or " injury "
The Inflammatory Response
28
______ causes the activation of a chemical in plasma called " Factor XII or Hageman Factor.
CELL INJURY
29
______is responsible for " ACTIVATING AT LEAST THREE SYSTEMS IN THE BODY
HAGEMAN FACTOR
30
Also known as Factor XII
Hageman factor
31
Also known as Factor XII
Hageman factor
32
The Hageman Factor is responsible for activating at least which 3 systems in the body ?
1. Kinin System 2. Clotting Cascade 3. Plasminogen System
33
Initiates " blood clotting "
CLOTTING CASCADE
34
Initiates "Dissolution" of blood clots
PLASMINOGEN SYSTEM
35
Hageman Factor activates Kallikhrein, a substance found in the local tissues, which causes ?
The precursor substance kininogen ti be converted to "bradykinin and other kinins.
36
Causes " local vasolidation " and changes in the capillary permeability which brings more blood to the injured area and allows WBCs to escape into the tissues
BRADYKININ
37
Why barrier defenses exist?
To prevent the ebtry of foreign pathogens and to serve as important lines of defense in protecting the body.
38
Any foreign pathogen that manages to get past the barrier defenses will encounter??
THE HUMAN INFLAMMATORY
39
The MPS ( Mononuclear Phagocyte System ) is composed primarily of?
LEUKOCYTES, LYMPHOCYTES, LYMPHOID TISSUES, AND NUMEROUS CHEMICAL MEDIATORS
40
Stem cells in the bone marrow produce two types of wbc or leukocytes, what is it?
1. Lymphocytes 2. Myelocytes
41
The key components of the immune system and consist T cells and B cells and natural killer cells.
LYMPHOcytes
42
The ______ can develop into a number of different cell types that are important in both the basic inflammatory response and the immune response.
Myelocytes
43
It is capable of MOVING OUSIDE OF THE BLOODSTREAM (diapedesis) and engulfing and digesting foreign material ( phagocytosis )
NEUTROPHILS
44
Myelocytic leukocytes that are NOT CAPABLE OF PHAGOCYTOSIS.
BASOPhils
45
Myelocytic leukocytes whose exact function is not understood. They are often foynd at the site of allergic reactions and may be responsible for removing the proteins and active components of the immune reaction fromt he site of an allergic response.
EOSINOphils
46
Monocytes or Mononuclear Ohagocytes are also called
MACROPHAGES
47
They are mature leukocytes that are capable of phagocytuzing an antigen.
Monocytes
48
Cellular defenses include
1. Blood cells ( lymphocytes ) T & B cells and Myelocytes ( neutrophils, eosinophils, basophils and macrophages )
49
The local reaction of the body to INVASION Or INJURY
Inflammatory Response
50
Cell injury causes the ACTIVATION of a chemical in the plasma called
FACTOR XII or Hageman Factor
51
Cell injury causes the ACTIVATION of a chemical in the plasma called
FACTOR XII or Hageman Factor
52
It is activated when Hageman Factor activates Kallikrein which causes the precursor substance kininogen to be converted to bradykinin and other kinins
Kinins System
53
Was the FIRST KININ identified and remains the one that us best understood.
BRADYKININ
54
It is the precursor to many substances called AUTOCOIDS , including cyclooxygenase, prostacyclin, and thromboxane.
55
These substances act like a LOCAL HORMONES that cause an EFFECT in the IMMEDIATE AREA and then are Broken down.
AUTOCOIDS
56
Autocoids includes ( P C L T )
1. Prostaglandins 2. Cyclooxygenase 3. Leukotrienes 4. Thromboxanes
57
Some of which augment in the inflammatory reaction and some of which BLOCK IT
Prostaglandin
58
Involved in INFLAMMATION and various PROTECTIVE ACTIONS in the body.
CYCLOOXYGENASE
59
Injury to a cell membrane causes the local release of
Histamine
60
Histamine causes "V" , which brings more blood and blood components to the are
Vasodilation
61
Histamine also stimulates
Pain reception
62
Some leukotrienes activated by arachidonic acid have a property called "Chemo___"
CHEMOTAXIS
63
Or HEAT, occurs because of the increased blood flow to the area.
CALOR
64
SWELLING , occurs because of the fluid that leaks into the tissues as a result of the change in capillary permeability
TUMOR
65
Or REDNESS , also related to the increased in blood flow caused by the vasodilation
RUBOR
66
Or PAIN ,comes from the activation of Pain fibers by Histamine ans the kinin system.
DOLOR
67
A response to cellular injury that can last from MINUTES to a FEW DAYS. It is protective and part of the process of TISSUE HEALING.
ACUTE INFLAMMATION
68
It may last WEEKS, MONTHS OR EVEN YEARS . IT CAN HARMFUL by stimulating more cellular damage and even causing healthy tissue to become scarred and or fibriotic
CHRONIC INFLAMMATION
69
Programmed in the "T"THYMUS GLAND and provide what is called cell- mediated immnunity
T CELLS
70
T cells develop into at least 3 different cell types
1. Effector or Cystotoxic T Cells 2.
71
T cells develop into at least 3 different cell types
1. Effector or Cystotoxic T Cells 2.
72
Found throughout the MPS in groups called clones
B CELLS
73
Programmed to identify specific proteins or antigens. They provide what is called HUMORAL IMMUNITY.
B cells
74
Produces Antibodies or immunoglobins, ehich circulate in the body and react with this specific antigen when it is encountered.
PLASMA CELL
75
The antibodies are released in the form of
IMMUNOGLOBINS
76
5 Dufferent types of IMMUNOGLOBINS
1. M (IgM) 2. IgG 3. IgA 4. IgE 5. IgD
77
5 Dufferent types of IMMUNOGLOBINS
1. M (IgM) 2. IgG 3. IgA 4. IgE 5. IgD
78
Antibodies produced AT FIRST EXPOSURE TO THE ANTIGEN
M ( IgM )
79
Found in tears , saliva, sweat , mucus and bile. It is secreted by plasma cells in the GI and respiratory tract and in epithelial cells. These antibodies react with SPECIFUC PATHOGENS taht are Encountered in exposed areas of the body.
IgA
80
It is present in SMALL AMOUNTS and seems to be related to ALLERGIC RESPONSES and to actuvation of Mast Cells
IgE
81
Aother identified immunoglobin whose role HAS NOT BEEN DETERMINED. Found primarily on B lymphocyte vell membranes so it may fubction in B - Cell differentiation
IgD
82
Contains antibodies made by MEMORY CELLS that circulate ans enter the tissue; most of the imuunoglobin found in the serum
IgG
83
It prevents viral REPLICATION and also suppress malignant cell replication and Tumor growth
INTERFERONS
84
Other Mediators are
1. Interferons 2. Interleukins 3. Thymosin 4. Tumor Necrosis Factor
