The function of neutrophils in the immune system are to kill off invading microbes in your bodies immune system.
Your neutrophils in your immune system circulate throughout your body in your bloodstream.
Then the neutrophils migrate to wherever the infection in your body is to kill off the bad and invading microbes.
Your neutrophils are very important to your bodies immune system and are the most common type of white blood cell in our bloodstream and are among the first immune cells to defend against infections in our bodies.
Neutrophils are also phagocytes, which ingest bacteria and other foreign cells and without them our bodies would continue to have illness and viruses and not be able to fight off the viruses and illnesses.
