How Do White Blood Cells Protect the Body from Infection?

White blood cells (WBCs) play a vital role in protecting the body from infection. They detect and destroy harmful pathogens like bacteria, viruses, and fungi. Some white blood cells engulf and digest invaders, while others produce antibodies to neutralize them. This immune response helps prevent illness and supports recovery. In cases of severe bacterial infections, doctors may prescribe antibiotics such as ceftriaxone injection. A trusted ceftriaxone injection supplier ensures the availability of this essential medication, which supports the immune system by eliminating bacteria, reducing the burden on white blood cells, and promoting faster healing and protection against complications.
