-
Erthropietin?
- Needs to get to the red marrow
- Liver releases it
- Kidney Activates it
-
What are the 3 Plasma Proteins?
- Albumin: made by the liver
- " should never leave circulation"
- Maintains Osmotic Pressure.
Globulins:antibodies used in the " presence of invaders".
Fibrinogen:clotting protein
-
Hemopoiesis
- Process by which blood is made
- * Location: Red Marrow
- * Hemocytoblast: immature connective tissue blood cells which red and white blood cells arise from
