Simply how the body reacts when it si infected?

When the body is infected, the immune system springs into action to identify and eliminate the invading pathogens, such as bacteria or viruses. Immune cells release signaling molecules called cytokines to recruit other immune cells to the site of infection, leading to inflammation, which helps to contain and destroy the invaders. Symptoms like fever and fatigue may occur as the body ramps up its defenses and reallocates energy to fight off the infection. Overall, this coordinated response aims to restore health and prevent further harm.
