Immune System Flashcards
Primary organs of IS
Bone marrow and thymus
Secondary organ of IS
Peyers patches
Peyers patches make up how much of IS?
70%
Purpose of vaccine
Create immunological memory w/o actually having the disease
When is the innate IS activated?
When surface barriers are breached
Innate response initiates and triggers….
Acquired response
Which is faster: innate or acquired?
Innate
Most important cell in adaptive response
Lymphocytes
Adaptive response _______ the innate response
Facilitates
Active vs passive immunity
Active - produced by administered foreign antigens
Passive - produced by administered antibodies
Which is permanent: active or passive immunity?
Active
Two types of active immunity
Natural - enviro exposure
Artificial - vaccine
Two types of passive immunity
Natural - breast milk
Artificial - injection of antibody
Humoral immunity deals with infectious agents in…
Blood and body tissues
Cell mediated immunity deals with __________ that have been infected
Body cells
What mediates innate, humoral, cell mediated?
Exterior defenses
Antibodies
T-lymphocytes
T cell –> regulator t cells –>
Helper T + suppressor T
T cell –> effector T –>
Cytotoxic T + memory T
Microscopic component of pathogen that causes immune response
Antigen
Explain epitope
Subunit of antigen that bind with t-cell or antibody and elicit immune responses
3 potential outcomes of antibody attaching to antigen
- Activate complement system
- Tag pathogen for destruction by B or T cells
- Neutralizes pathogen
MHC
Major histocompatibility complex proteins
MHCs allow immune cells to…
Recognize/communicate with eachother
HLA
Human leukocyte antigens
Predispose susceptibility to AI disease
HLAs
Neutrophils ____ after killing
Die
Macrophage nickname
Large eaters
Macrophages release interleukins that….
Present antigens to helper T cells to elicit adaptive immune response
Type of cell that multipies in allergic disorders
Eosinophils
2 cells that circulate in peripheral blood and react to allergic disorders
Basophils
Mast cells
Interferons role
Inhibit tumor growth
Most aggressive WBCs in IS
NK
Optimal length of exss on immune system
30 min
Strenous exss may ____ IS
Harm
Most common anaphylactic shock
Bee sting
Atopy
IgE mediated diseases - genetic predisposition to produce too much IgE —–> hypersensitivity
4 types of hypersensitivity
- Allergic reactions
- Cytotoxic rxn to self antigen
- Immune complex hypersensitivity
- Cell mediated
What is produced instead of IgG in type 1 hypersensitivity?
IgE
Type 2 hypersensitivity: body’s own tissue IDed as _________
Antigen
Outcome of type 3 hypersensitivity
Acute inflammation/tissue injury
Response in type 4 hypersensitivity
Delayed
Ex: graft vs host
3 populations at highest risk for HIV/AIDS
Gay men
Sex workers
IV drug users
AIDS
Acquired immune deficiency syndrome
AIDS caused by
Virus
In AIDS, there is a dec in what kind of cell?
Helper T
Benefit of exercise for patients with HIV
Can increase CD4 cells and delay symptoms
Can people with AIDS exercise?
Yes if they get medical clearance
Exercise may provide _______ in HIV/AIDS pts
Pain relief
CFS
Chronic fatigue syndrome
Monitor this in pts with CFS while you exercise them
Vital signs
It has been proven that exercise can have this outcome for pts with CFS
Decreased fatigue intensity
Name dat antibody:
Largest
IgM
Name dat antibody:
Expressed on surface of B cells
IgM + IgD
Name dat antibody:
Major antiviral/antibac antibody in blood
IgG
Name dat antibody:
Defends external body surfaces
IgA
Name dat antibody:
Bound to receptors on mast cells/basophils
IgE
Name dat antibody:
Predominant antibody on B lymphocytes
IgD
Type of T cell that prevents autoimmune disease
Regulatory/supressor
Cellular immunity cannot be transferred _________ to another human
Passively
4 potential outcomes if an antigen gets past external defenses
- B lymphocyte recognizes and produces antibodies to neutralize
- T lymphocyte recognizes and cytokines kill
- Cytotoxic T cell recognizes and destroys (virus)
- Complement system
3 overall effects of aging on IS
- Dec resistance to pathogens
- Inc number of tumors
- Inc autoimmune disorders
Production of autoantibodies is seen in…
Autoimmune diseases
Humoral therapy for AI disease
Remove antibodies
Cell-mediated therapy for AI disease
Immunosuppressive and cytotoxic therapies
Autoimmune disease triad
- Genetic vulnerability
- Environmental trigger
- Leaky gut
SLE
Systemic lupus erythematosus
DLE
Discoid lupus erythematosus
Inflammation location of DLE
Just skin
Inflammation location of SLE
Organ/body system
Main symptom of SLE/DLE
Joint pain/swelling
Biggest PT consideration for SLE
Avoid bedrest
Most common MS disorder of US
fibromyalgia
Major muscle affected significantly in FMS

FMS has a strong connection with..
Anxiety
4 treatments for FMS
- Stress mgt
- Meds
