Types of Formed Elements
Formed elements are the cellular components of blood. They include red blood cells, white blood cells, and platelets. Each type of formed element has a unique structure and function.
| Name | Description | Function |
|---|---|---|
| Red blood cells | Biconcave disks that contain hemoglobin | Transport oxygen |
| White blood cells | Cells that defend the body against infection | Various functions, including phagocytosis, antibody production, and cell-mediated immunity |
| Platelets | Small, disk-shaped cells that are involved in blood clotting | Form clots to stop bleeding |
Formed elements differ from other blood components, such as plasma and serum, in that they are cellular and contain nuclei.
Microscopic Examination of Formed Elements
Microscopic examination of formed elements is an essential technique for diagnosing and monitoring blood disorders. To prepare a blood smear for microscopic examination, a small drop of blood is placed on a glass slide and spread out into a thin layer.
The slide is then stained with a dye, such as Wright’s stain, which makes the different types of formed elements easier to identify.
Once the slide is stained, it is examined under a microscope. The different types of formed elements can be identified based on their size, shape, and staining characteristics. Red blood cells are typically round and biconcave, while white blood cells are larger and have a more complex shape.
Platelets are small and disk-shaped.
The morphology of formed elements can provide important information about their function and health. For example, abnormal red blood cell morphology can indicate anemia, while abnormal white blood cell morphology can indicate leukemia.
Clinical Significance of Formed Elements
Formed element counts and morphology can be used to diagnose and monitor a variety of diseases. For example, a low red blood cell count can indicate anemia, while a high white blood cell count can indicate infection. Abnormal platelet counts can indicate bleeding disorders or clotting disorders.
Accurate formed element analysis is essential for clinical practice. By understanding the different types of formed elements and their clinical significance, healthcare professionals can make informed decisions about the diagnosis and treatment of blood disorders.
