This document summarizes white blood cells (WBCs), also known as leukocytes. It discusses their formation in bone marrow, types including granulocytes (basophils, eosinophils, neutrophils) and agranulocytes (lymphocytes, monocytes). It describes their characteristics and functions in inflammatory response and fighting infection. The document also lists some diseases related to abnormalities in WBC counts, such as leukopenia, leukemia, and leukocytosis.

3. Outline of The Topic :-
 Introduction ,
 Formation of WBC ,
 Types of WBC ,
 Discuss about Types & their functions ,
 Diseases related with Leucocytes .

4. WHITE BLOOD CORPUSCLES
or ,
LEUCOCYTES
 White Blood Corpuscles are also known as
Leucocytes , as they are colourless due to lack of
Haemoglobin .
 There are about 6,000-8,000 mm of WBC for 1ml of
blood .

5. Formation of WBC :-
 Leucocytes are formed in the Red
Bone Marrow of many bones .
 They can also be formed in
lymphatic tissue .
 They live for about 13-20 days .

6. Types of WBC :-

7. Agranular or Agranulocyte :-
LYMPHOCYTES :
• Smallest WBC .
• Small amt. Of Cytoplasm .
• Two types ,-
1) T Lymphocytes ,
2) B Lymphocytes ,
3) NK Cells .

8. MONOCYTES :
• Largest of WBCs .
• Dark kidney bean shaped
neucleous .
• Phagocytic .
* Functions :
Monocytes are acts as antigen
processing .

9. Granular or Granulocyte :-
 BASOPHILS :
• Basophils are 10-15 micron in diameter .
• they have “ S “ shaped neucleous .
• The granules in the basophils contain “
Histamin “ & “ Heparin “ .
* Function :
Basophils have inflammatory reaction .

10. EOSINOPHIL :
• Large , numerous granules .
• 2-6 % of WBC count .
• Eosinophils are 10-15 micron in diameter .
* Function :
Eosinophils primarily deals with Parasitic
infectious and allergic reactions .

11. NEUTROPHIL :
• Granules are small and numerous .
• Highly active .
• 65 % of WBC count .
* Function :-
Neutrophils defend against bacterial or fungal
infection .

12. Diseases Related to Leucocytes :-
 LEUKOPENIA ,
 LEUKEMIA ,
 LEUCOCYTOSIS .
