What is the primary function of eosinophils?

Eosinophils are a type of white blood cell that play a crucial role in the immune system, particularly in combating parasitic infections and mediating allergic responses. Their primary function involves the destruction of larger pathogens, such as parasites, that are too big for other immune cells to handle effectively. Eosinophils contain granules filled with enzymes and toxic proteins that can be released to damage the membranes of these parasites.

In addition to their role in fighting infections, eosinophils are also involved in the inflammatory response associated with allergies and asthma. They can modulate the activity of other immune cells and contribute to the overall immune response during allergic reactions. This dual role makes them essential in both combating infections and managing conditions related to hypersensitivity reactions.

The other options refer to functions associated with different types of immune cells or processes. For example, antibody production is primarily the role of B cells, while phagocytosis of bacteria is mainly carried out by neutrophils and macrophages. Regulation of blood clotting is related to platelets and factors in the coagulation cascade, rather than eosinophils. Therefore, the choice highlighting the role of eosinophils in destroying parasites and responding to allergies accurately reflects their specific and significant functions within
