White blood cells (WBCs) are essential components of the immune system, protecting the body from infections and diseases. They identify and attack harmful invaders like bacteria, viruses, and other pathogens. Different types of WBCs, such as neutrophils and lymphocytes, play specific roles in detecting threats, producing antibodies, and destroying infected cells. When bacterial infections occur, treatments like ceftriaxone injection are often prescribed to support the body’s defense by eliminating bacteria. The ceftriaxone injection distributors ensure healthcare providers have access to this vital antibiotic, aiding in rapid infection control and supporting the immune system's efforts to restore health effectively.
