Anemia:
|
a condition, not a disease in which there is a “reduced oxygen-carrying ability of the blood” –
|
|
|
Types of anemia:
|
Nutritional Anemia: Pernicious Anemia: Aplastic Anemia:
|
|
|
Nutritional Anemia:
|
from an inadequate diet (need amino acids, iron, Vit B12)
|
|
|
Pernicious Anemia:
|
from the inability to produce intrinsic factor
|
|
|
Aplastic Anemia:
|
from the destruction or inhibition of the red bone marrow
|
|
|
Polycythemia:
|
an abnormally high number of RBC’s, increasing the viscosity of blood causing sluggish flow (hematocrit of 80% or more)
|
|
|
Types of polycythemia:
|
Polycythemia vera: Relative Polycythemia: Secondary Polycythemia: Thalassemia:
|
|
|
Polycythemia vera:
|
an increase in blood volume and red blood cells from hyperactivity of bone marrow (may be caused by bone marrow cancer)
|
|
|
Relative Polycythemia:
|
relative increase in the number of red blood cellsas a result of loss of the fluid portion of the blood (may occur in dehydration, burn, and shock)
|
|
|
Secondary Polycythemia:
|
due to chronic hypoxia, which triggers excess RBC production (high altitude, pulmonary disease, etc.)
|
|
|
Thalassemia:
|
a genetic disease in which cells are not able to produce enough ∂ or ß chains for Hb (body responds by producing large #’s of new RBC’s, with low [Hb])
