Neutrophils typically take about 14 to 21 days to develop from hematopoietic stem cells in the bone marrow. Once fully mature, they enter the bloodstream and can circulate for about 5 to 7 days before migrating to tissues in response to infection or inflammation. Their rapid turnover and short lifespan are critical for effective immune responses.
