👉 Exion is a medical term used to describe the process of the immune system responding to an infection. It involves the release of antibodies and other immunological components, which can help fight off the virus or bacteria that cause the infection. Exions are often associated with a specific type of immune response called complement-mediated immunity, which involves the production of a complex protein called C3a, which triggers the formation of exons to engulf the invading pathogen.
