Granulocytes
Granulocytes are a type of white blood cell that play a crucial role in the immune system. They are characterized by the presence of granules in their cytoplasm, which contain enzymes and other substances that help fight infections. There are three main types of granulocytes: neutrophils, eosinophils, and basophils, each with specific functions in responding to different types of pathogens.
Neutrophils are the most abundant granulocytes and are primarily responsible for attacking bacteria and fungi. Eosinophils are involved in combating parasitic infections and play a role in allergic reactions, while basophils release histamine during inflammatory responses. Together, these cells help protect the body from various threats.
