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]
