Types of WBC's NEVER
LET MONKEYS EAT BANNANAS |
Neutrophils
Lymphocytes Monocytes Esinophils Basophils |
|
|
Monocytes
|
1-6% of WBC's
Circulate in blood and become macrophages in tissues Phagocytic -Macro=big, Phage=eater |
|
|
Lymphocytes
|
20-35 %
Reside mostly in lymphoid tissues T-cells B-cells |
|
|
Granulocytes
|
-Neutrophils- most prevelant 50-75%, eat bacteria, (phagocytic)
-Eosinophils- 1-3% of WBC's (good for Tapeworms) Basophils-hystomine |
|
|
Dendritic cell
|
-Antigen presenting cell
-activates T-cells and B-cells Resides in skin and various organs Migrate to lymph to present Ag |
|
|
Innate Immunity (non-specific response)
|
1st line of defense-physical barriers
-skin,mucous membrane, ciliated epithlium. |
|
|
Innate Immunity:
2. Inflammatory response happens when... |
Physical defenses broken- tissue damage.
cytokines are released- ex are histamines, and interlukens. >call for help >Induce fever >increase capillary permeability |
|
|
Innate Immunity:
3. Complement System. |
a. proteins that circulate in blood in inactive form
b.Activated by bacteria or Ab bound to bacteria. c.Activation leads to cascade of rxn resulting in pores in bacteria cell call on lysis. |
|
|
Aquired immunity (specific response)
|
B-cells-Ab mediated immunity
( humoral response) a. Produce and insert Ab on surface: Immunoglobulin (IgA passed through breast milk) b. Plasma cells c.memory cells |
|
|

|
Blood grouping:
