* Neutrophils: These are the most abundant white blood cells and are the first responders to infection. They engulf and destroy bacteria and other pathogens.

* Macrophages: These are large, phagocytic cells that develop from monocytes. They are found in tissues and play a crucial role in immune responses by engulfing pathogens, cellular debris, and foreign particles.

* Eosinophils: While primarily involved in fighting parasitic infections, eosinophils also have some phagocytic capability, particularly against larger parasites.

Note: While lymphocytes (B and T cells) are crucial components of the immune system, they are not directly phagocytic. Their role involves recognizing specific antigens and triggering immune responses.
