White blood cells (WBCs) play a crucial role in the immune system, defending the body against infections. Their life cycle begins in the bone marrow, where stem cells develop into various types of WBCs such as neutrophils, lymphocytes, and monocytes. Once matured, they enter the bloodstream, ready to identify and neutralize pathogens. WBCs have varying lifespans depending on their type and function. During infections, antibiotics like ceftriaxone may be prescribed to support the immune response. If you're in the pharmaceutical industry or healthcare sector, choosing a reliable ceftriaxone supplier ensures consistent quality and efficacy in treating bacterial infections effectively.
