Here's why:

* Lymphocytes are responsible for specific immunity. They recognize and target specific pathogens through antigen recognition. They do not engulf and destroy pathogens directly like phagocytes do.

Here's a breakdown of the main types of lymphocytes:

* T lymphocytes (T cells): They directly attack infected cells or stimulate other immune cells.

* B lymphocytes (B cells): They produce antibodies, which bind to pathogens and tag them for destruction by other immune cells.

Phagocytic white blood cells include:

* Neutrophils

* Macrophages

* Eosinophils

* Dendritic cells

These cells engulf and destroy pathogens, cellular debris, and other foreign material.
