Granular Leukocytes

A

Basophils

17
Q

Lymphocytes

A

25-30% of all leukocytes

18
Q

3 Functional Categories of Lymphocytes

A 
B Lymphocytes (B Cells)
T Lymphocytes (T Cells)
Null Cells
19
Q

B Lymphocytes

A
  • humorally mediated immune response

- develop in bone marrow and produce antibodies, differentiate into plasma cells

20
Q

T Lymphocytes

A
  • cell-mediated immune response (does not involve antibodies)
  • develop in thymus
  • release singling molecules (cytokines)
21
Q

Monocyte

A
  • 3-8% of all WBCs
  • kidney shaped nucleus
  • differentiate into macrophages
22
Q

Neutrophils

A
  • 60-70% of WBCs
  • first responders to infection and microbes
  • multi-lobed nucleus is connected by chromatin threads
23
Q

Eosinophils

A
  • less than 4% of WBCs
  • first responders to parasites and phagocytose antigen-antibody complexes
  • bi-lobed nucleus connected by chromatin
24
Q

Platelets (Thrombocytes)

A
  • less than 14 day lifespan
  • no nucleus
  • become activated when endothelial lining of blood vessel is disrupted and they come into contact with sub endothelial collagen
