Final answer:
Neutrophils are phagocytic white blood cells that are most prevalent among all WBC types. They form the foremost defense against infections by traveling in the bloodstream and responding quickly to infected areas through phagocytosis.
Step-by-step explanation:
It is true that granulocytes called neutrophils are phagocytic and are the most numerous of all white blood cell types. Neutrophils are a type of white blood cell, also known as leukocytes, that play a crucial role in the body's immune response. They are characterized by their granular cytoplasm and multilobed nucleus.
As part of the body's first line of defense, they travel throughout the bloodstream and are usually the first immune cells to arrive at the site of an infection. These cells are capable of phagocytosis, which involves engulfing and destroying pathogens.
The bone marrow produces a significant number of neutrophils daily to maintain a sufficient count to effectively fight infections.
