A » The immune system is like your body's personal army, constantly on patrol to protect you from infections. When harmful invaders like bacteria or viruses enter, the immune system responds by sending white blood cells to attack and destroy them. It also creates antibodies, which are special proteins that recognize and neutralize these invaders. Over time, it learns and remembers how to fight specific threats, keeping you healthy and strong.

A »The immune system fights infections through a multi-step process. When a pathogen enters the body, it triggers an immune response. White blood cells, such as neutrophils and macrophages, engulf and destroy the invader. For example, when bacteria cause pneumonia, the immune system produces antibodies to neutralize the bacteria, and white blood cells work to eliminate the infection.
