Additional Information
Neutrophils are the most abundant type of white blood cell in the human body, accounting for approximately 50-70% of the total leukocyte count. They play a crucial role in the host defense against bacterial infections by engulfing and digesting foreign particles and bacteria. Neutrophils are also involved in the process of inflammation, where they release chemical mediators that attract other immune cells to the site of infection.
Neutrophils are produced in the bone marrow and circulate in the blood stream, where they can be activated by various stimuli to undergo a process called degranulation, in which they release their granule contents into the surrounding tissue.
