34 year old Pt. HIV has developed into AIDS
upstream
Direct
Pt. has come in contact with someone who has HIV or AIDS.
T<h> Cells become infected by the virus
Indirect
HIV virus enters the body through blood, oral, vaginal, or anal sex, and mucous membrane.
downstream
indirect
T cells begin to die due to the virus
immune system begins to collapse
It becomes easier to catch diseases
The right disease can cause death
Immediate
lymph glands begin to swell
soreness
fever
fatigue
AIDs
If left untreated small diseases and infections can kill you
Develops quickly
Aquired Immunodificency Disorder
when HIV becomes AIDS immune system in compramised
Your body cannot fight foriegn invaders
which means your immune system is difficent
Immune system
Attacks T cells
T cells attack foreign invaders
B cells are not activated
No antibodies are made against the antigens
Inhibits adaptive immune response
background
ANATOMY
T cells
Attacks intracellular antigens
NK Cells
Natural killer cells
Kills what the T cells do not recognize
B cells
Humoral immunity
Produces antibodies
Each B cell produces a specific anitbody
Neutrophils
Phagocytic cells
Eats infected cells
Monocytes
Chief phagocytic cell
Makes macrophages
Eats cellular debris
Unwanted things in the body
Red bone marrow
Where B and T cells are made
Only B cells stay to proliferate and mature
Thymus
T cells move here to proliferate and mature
Spleen
Tonsils
All places where the cells perch themselves and look for antigens and pathogens
Lymph nodes
PHYSIOLOGY
Bacteria
Divides outisde the cell
Causes infections
Causes infections in the body
Virus
Needs host
Can only be fought by the body
Lytic
gets inside bacteria
destroys host DNA
Replicates

Lysogenic
gets inside bacteria
merges into the cells DNA
Lets cell divide

Antibiotics do not work
Defenses
Innate
Non specific
2 lines of defenses
1st line of defense
Skin
Mucous
2nd line of defense
NK cells
Kills what the specific defenses do not notice
monocytes
neutraphils
Eats infections
Inflammation
adds pain so the area is forced to rest
Adaptive
Specific
3rd line of defense
B cells
T cells
AIDS
It is HIV with a severely compromised immune system
HIV
Inhibits immune system
Destroys helper T cells
virus develops more overtime
Immune system starts to become weak
Immune system is no longer functional
