Plasma protiens synthesized by liver cells: albumins 54% of plasma proteins, globulins 38, fibrinogens 7, immunoglobulins (antibodies) Except for lymphocytes, formed elements do not divide once they leave red bone marrow. Plurpipotent stem cells - cells that have the capacity to develop into many different types of cells: develop into 2 types of cells: Myeloid stem cells: begin and complete development in red bone marrow and give rise to rbcs, platelets, monocytes, neutrophils, eosinophils, and basophils, progenitor cells.
