Granulocytes

Definition

Granulocytes are a type of white blood cell characterized by the presence of granules in their cytoplasm. They play a crucial role in the immune response by fighting infections and inflammation.

5 Must Know Facts For Your Next Test

1. Granulocytes include neutrophils, eosinophils, and basophils, each with distinct functions.
2. Neutrophils are the most abundant granulocytes and are essential for combating bacterial infections.
3. Eosinophils are primarily involved in combating parasitic infections and allergic reactions.
4. Basophils release histamine during allergic responses, playing a key role in inflammation.
5. Nutrition can impact granulocyte function, with deficiencies in certain vitamins (like vitamin C) impairing their effectiveness.
