White blood cells (WBCs) play a vital role in defending your body against infections and diseases. They identify and destroy harmful bacteria, viruses, and other pathogens that invade your system. When an infection occurs, WBCs increase in number to fight off the invaders. Treatments like antibiotics, including ceftriaxone injection distributors providing high-quality medications, support the immune system in managing severe bacterial infections. Maintaining healthy white blood cell levels is essential for strong immunity and overall well-being.
