|
The percentage of the blood that consists of red blood cells.
|
Hematocrit
|
|
|
60-80% of blood plasma proteins.
Provides the osmotic pressure needed to draw water from the surrounding tissue fluid into the capillaries. Produced by the liver. |
Albumin
|
|
|
Plasma protein that functions in transporting lipids and fat-soluble vitamins. Also functions in immunity.
Alpha and beta are produced by liver. Gamma are produced by lymphocytes. |
Globulin
|
|
|
Plasma protein that is important in clotting.
Produced by the liver. |
Fibrinogen
|
|
|
Inadequate amount of vitamin B12.
|
Pernicious anemia
|
|
|
Deficiency of red blood cells due to the destruction of bone marrow.
Caused by chemicals or radiation. |
Aplastic anemia
|
|
|
Abnormal excess of erythrocytes.
|
Polycythemia
|
|
|
Hemoglobin levels are constantly decreased, but red blood cell size is the same.
Occurs as a result of hemorrhage. |
Normocytic anemia
|
|
|
Hemoglobin synthesis failure/insufficiency.
Caused by iron deficiency. |
Microcytic anemia
|
|
|
Deficiency of Vitamin B12, folic acid, or both.
|
Macrocytic anemia
|
|

|
What is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart?
|
System circulation
|
|
|
What circulation is the portion of the cardiovascular system which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart?
