The leukocytes of innate immunity can be, according to their functions, leukocytes with phagocytic activity and natural killer leukocytes or NK.

Explanation:

Innate immunity is a natural and non-specific immune response of an organism, which implies an immediate response but does not extend over time. The innate cellular response includes phagocytes and natural killer cells or NK.

- Phagocytes or leukocytes with phagocytic function can identify and eliminate foreign agents generally, without discriminating between the type of agent. Macrophages, dendritic cells and neutrophils belong to this cell group.

- NK cells are able to eliminate cells in the body infected by microorganisms, as these cells are not recognized as their own due to changes in their cellular markers. Tumoral and virus-infected cells can be eliminated by NK. Basophils, eosinophils and mast cells belong to this group of NK cells.
