RBC |
4.2-6.2 Contains hgb Produced continously in red bone marrow |
|
|
What happens when RBCs don't deliver enough oxygen to the tissues? |
Kidneys release erythropoietin --> Carried to bone marrow --> Initiates mature RBC formation |
|
|
Hgb |
12-18% Carries oxygen --> Cells Carries carbon dioxide from cells --> Lungs |
|
|
Increased Hgb |
Polycythemia Dehydration COPD |
|
|
Decreased Hgb |
Anemia Hemorrhage SOB (when moving around) |
|
|
Hct |
37-54% Measures the volume % of RBCs in the whole blood |
|
|
Increased Hct |
Dehydration Severe burns Shock |
|
|
Decreased Hct |
Anemia Leukemia Hemorrhage |
|
|

<15 males < 20 females Measures how quickly erythrocytes settle at the bottom of a test tube contain a blood sample Measured in seconds |
|
|
Increased ESR |
Tissue destruction Inflammation Incfection Necrosis Edema Allergic reaction Rheumatoid arthritis |
|
|
Decreased ESR |
A disease that may cause increased RBC |
|
|
Plt |
150,000-400,000 Plays tolle in hemostasis (clotting) Produced in bone marrow Short life span |
|
|
