Study Notes
Granular Leukocytes
- Comprise three types: Neutrophils, Eosinophils, and Basophils.
Neutrophils
- Represent 50-70% of circulating white blood cells (WBCs).
- Act as the first responders to infection by engulfing microorganisms.
Eosinophils
- Account for 2-4% of circulating WBCs.
- Primarily defend against large parasites, such as worms.
- Help to moderate the severity of allergic reactions.
Basophils
- Make up 0.5% of circulating WBCs.
- Contain histamine in their granules, contributing to inflammation.
Agranular Leukocytes
- Comprise two types: Monocytes and Lymphocytes.
Monocytes
- Constitute about 5% of circulating WBCs.
- Exit the bloodstream to transform into macrophages, which engulf pathogens and debris.
Lymphocytes
- Account for approximately 30% of circulating WBCs.
- Play a crucial role in the immune response.
Types of Lymphocytes
- Include B lymphocytes and T lymphocytes.
B Lymphocytes
- Responsible for antibody immunity by producing antibodies.
T Lymphocytes
- Responsible for cell-mediated immunity by directly targeting and attacking invaders.
