Name of the Teacher: Raji V.R.                                  Std: X
Unit: The Strategy of defense and treatment         Duration: 15 minutes
Topic: The different types of WBCs.


Objective

          The different types of white blood cells are described using power point presentation.

Content Summary

          Based on the presence or absence of granules WBCs are classified into granulocytes and agranulocytes. Granulocytes have large granules in the cytoplasm. This includes neutrophils, eosinophils and basophils. Agranulocytes donot have granules in the cytoplasm. This includes lymphocytes and monocytes.

          Neutrophil has several lobes and form 65% of WBC count. It is involved in phagocytosis. Eosinophils have two lobes in the nucleus. It forms 2-5% of WBC count. It is involved in allergic reactions. Basophils are least in number. It contains histamine.

          Lymphocytes are smallest WBC. Presence of large nuclei. Account for 25% of WBC count. It produces antibodies. Monocyte is the largest of WBC. Dark kidney shaped nucleus. Highly phagocytic cells.





Teaching learning resources used

      Power point presentation of different types of white blood cells downloaded from :  www.successlink.org/lessons/7500/7702/WBC%20notes.ppt

     This power point presentation is very simple and is easy to understand. Here the pictures and details of different types of WBCs are mentioned. It is very helpful to the pupil to understand the different types of WBCs.

Introduction

·       What are the different types of blood cells?

·       What is RBC & WBC?

·       From where WBCs are produced?

·       Does WBCs have nucleus?

·       What are the different types of WBC?

Presentation

 Power point presentation of different types of WBCs is shown.

Consolidation

Students write down the notes.WBCs are classified into two groups namely granulocytes and agranulocytes.

    Granules are present in granulocytes. This includes:
·       Neutrophil [multi lobed     nucleus]
·       Eosinophil [double lobed nucleus]
·       Basophil [least in number]

  Granules are absent in agranulocytes. This includes:
·       Monocytes [largest WBC]
·       Lymphocytes [smallest WBC]

Pupil listens and observes carefully.





   Formative Evaluation Procedure

Review

1.    How WBC is classified?
2.    Name the WBCs which come under the group granulocytes?
3.    Name the WBCs which come under the group agranulocytes?
4.    Is Neutrophil single lobed or multi lobed?
5.    How many lobes are present in eosinophils?
6.    Which is the smallest WBC?
7.    Which is largest WBC?

Follow up Activity

1.    What are the functions of the different types of WBCs?
2.     Named below are the different types of WBCs. Box contains its specific features. Examine both and pair them correctly.
