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.

Objectives

  • Discuss the characteristics of leukocytes, erythrocytes, and thrombocytes that are normally present in peripheral blood.
  • Compare and contrast the nuclear and cytoplasmic characteristics of each of the normal peripheral blood cells.
  • Evaluate the roles and functions of normal peripheral blood cells.
