Which white blood cells (wbcs) make up 50-70% of the circulating white blood cells, and are very active phagocytes, that specialize in attacking and digesting bacteria?

Nuetrophils are the most abundant luekocytes (white blood cells).

Explanation: Nuetrophils also known as granulocytes because they have a granule in their cytoplasm, are the most abundant phagocytic white blood cells. They are the first ones to arrive at the site of infection by injury, bacteria or during apoptosis (programmed cell death) in response to chemotaxis and inflammation feedback loops. They bind to bacterial receptors and engulf(digest) them together with any other foreign matter and dead cells.
