During infection what does the body release?

During an infection, the body releases various substances, including cytokines, which are signaling molecules that help regulate immune responses. White blood cells, such as macrophages and neutrophils, are activated and migrate to the infection site to combat pathogens. Additionally, the body may produce fever-inducing substances to raise body temperature, creating an inhospitable environment for the invading microbes. Overall, these responses aim to contain and eliminate the infection.
