This course covers the basics of normal peripheral blood cell morphology, including appearance, kinetics, and function of red blood cells, leukocytes, and platelets. It is assumed that students have a basic knowledge of the principles of cell morphology, and of preparation and staining of a Wright's stained peripheral blood smear.
