"granulocyte"的定义和意义

What is a "granulocyte"?

A granulocyte is a type of white blood cell characterized by the presence of granules in its cytoplasm. They play a vital role in the human body's immune response by defending against invading pathogens. The three main types of granulocytes are neutrophils, eosinophils, and basophils. Neutrophils are the most abundant and are highly efficient in engulfing and destroying bacteria. Eosinophils are involved in combating parasitic infections and regulating allergic responses. Basophils release chemical mediators that contribute to inflammation and allergic reactions. Together, these granulocytes work in harmony to protect the body from harmful pathogens and maintain overall immune health.
