White blood cells are the body’s defense system against infections. When harmful bacteria, viruses, or fungi enter, white blood cells quickly identify and attack them. Neutrophils rush to the infection site, engulfing and destroying invaders. Lymphocytes, such as T-cells and B-cells, provide targeted immunity by producing antibodies and coordinating responses. Macrophages clear away dead cells and pathogens, supporting healing. This immune activity reduces infection and prevents its spread. In severe bacterial cases, doctors may prescribe antibiotics. For example, healthcare providers often rely on ceftriaxone injection distributors to supply hospitals with effective treatments that complement the natural action of white blood cells.
