White blood cells (WBCs) are crucial defenders in your immune system, protecting the body from infections, bacteria, and viruses. They identify harmful pathogens, attack them, and support healing. Different types of WBCs have specialized roles neutrophils fight bacteria, lymphocytes create antibodies, and monocytes clean up dead cells. When the body faces a strong bacterial infection, doctors may prescribe antibiotics such as ceftriaxone injection. A reliable ceftriaxone injection supplier ensures the availability of this vital medication for hospitals and clinics. Without sufficient white blood cells, the body becomes vulnerable to illness, making them essential for maintaining health and immunity.
