Patho Final Exam Flashcards
1
Q
- Lymph Node Function
- Thymus Function
- T-cell origin
- T-cell function
- Largest Lymphatic Organ
A
- drain body tissues and return to the blood as plasma
- enable lymphcyte to develop in to T cells
- T-bone marrow, mature in the thymus
- Attack foreign or abnormal cells
- Spleen
2
Q
- Function of the Spleen
- Function of the Tonsils
- How are antibodies used?
A
- Macrophages, cell debris, process hemoglobin
- protect against airborne/ingested pathogens
- B-cells in response to antigen, 1 set of Ig
3
Q
- IgG
- IgA
- IgM
- IgE
- IgD
A
- Antibacterial/Viral. 80-85% of plasma antibodies
- Body surfaces, respiratory/GI tract
- FIRST responder, too large to cross membrane
- Mast Cells–> histamine/heparin
- B cells, antigen receptor (breaks down)
4
Q
- Neutrophils
- Eosinophils
- Basophils
- Monocytes
- Macrophages
A
- 60% WBC, phagocytosis
- Parasitic, Allergic, Lung/Skin Infections
- Release histamine, Contain Heparin
- Devour invading organisms
- Migrate to tissue to devour, inflammation
5
Q
- Allergy
- Autoimmunity
- Alloimmunity
A
- anything NOT found in the individual
- Does not recognize own antigens- Tcells damage tissue
- attacks transplanted tissue/fetus. Own species
6
Q
Hypersensitivity
- IgE mediated
- Tissue/Cytolytic/Cytotoxic
- Immune Complex Mediated
- Cell Mediated
A
- Anaphylaxis, Penicillin, basophils–> release histamine
- IgM/IgG, Cell lysis, ABO incom, hemolytic anemia
- Anitgen/Antibody complex, vessel walls/tissue, inflammation Arthus, Lupus
- T-Cells, lymphokine, TB dermatitis, transplant rejection
7
Q
- Prostaglandins
- Histamines
- Edema
- 2nd line defense cells
- Activator of inflammation
A
- Inflammation-remove harm
- inc permeability of capillaries to WBCs-infected tissue
- Leakage of plasma proteins
- Mast, dendritic, blood (rbcs, wbcs, platelets, granulocytes)
- Mast cells, closest
8
Q
- Histamin 1
- Histamine 2
- Histamine 3
A
- dilate blood vessels and contract smooth muscle
- stimulate heart rate and gastric secretion
- regulate histamine from neurons
9
Q
- Early phase of inflammation
- Late phase inflammation
- 3rd line of defense/Acquired Immunity
A
- fever, leukocytosis, plasma protein synthesis (8-10days)
- Dense infiltration of lymphocytes & macrophages
- Exposure to various antigens
10
Q
Acquired Immunity Processes
- Antigens/Immunogens
- Humoral Resonse
- Cell mediated Immunity
- B & T together
A
- Binding/Elicits Immune response
- Immediate against bacterial/viral infection
- Rejects transplanted organs–> T cells
- needed for a normal immune response
11
Q
- Active Immunity
- Passive Immunity
- Titer
- Self antigens
- Inflammatory Process
A
- Long-term acuired antibody protection
- Not permanents, trasferred placent–> fetus
- Concentration of antibody
- Doesn’t recognize as immunogenic, TOLERANCE
- Inc WBC, thrombus, macroscopic inflammation, microscopic accumulation of fluid
12
Q
- Inflammation Signs
- Bradykinin
- Leukotrienes
- Lysozymes
- Lymphadenopathy
A
- Heat, hardening, pain, edema, redness
- W/ Prostaglandin, PAIN, permability, smooth muscle contraction
- Histamine like effect, prolonged response, later stage 2nd line
- Body secretions KILL bacteria
- proliferation of lymphocytes and monocytes, enlarged lymph
13
Q
Types of T Cells
- Cytotoxic
- Helper
- Regulatory
- Memory
A
- Disrupts membranes and destroy internal environment
- Help B-cells to mature>release macrophage>activate cytotoxic
- Tolerance-abolish-Autoimmune
- Pattern Recognition
14
Q
- Bacteria
- Virus
- Fungi
- Yeast
- Mold
A
- 1 celled no nucleus reproduce by cell division
- DNA and RNA, no metabolism. Use host cells
- Non photosynthetic microbe asexual has a nuclues. Damage tissue
- Spheres, Facultative anaerobe
- Mutlinucleated aerobic microbe
15
Q
- Interferons
- Cyclosporins
- Complement System
- Infant T-Cell response
- Elderly T-Cell Response
A
- Immunomodulator Agent–>Slow tumor cell division
- Supress production of interferon-y
- Can destroy pathogens directly
- Slow Tcell development-depressed inflammatory function (neutrophils)
- Inc Autoantibodies, Deficient T-cell/Antibody production
16
Q
Complement System
- Classical Pathway
- Alternate Pathway
- Lectin Pathway
- Final Resut
A
- Antibody attaches to antigen > C1 Complex >Serine Protease > C3
- Young C3 and pathogen (innate immunity) > thioester bond > C3
- MCL binds to carbohydrate > C3
- MAC (membrane attack complex)
