Normal Peripheral Blood Cells
Continuing Education Credits
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.
- Identify images of the various types of normal peripheral blood cells.
