Final answer:
The mucosal immune system, IgE, and eosinophils evolved as a defense against parasitic worms.
Step-by-step explanation:
The mucosal immune system, IgE, and eosinophils have evolved as a defense against parasitic worms. These components work together to provide protection against the invasion of parasitic worms into the body. IgE, a type of antibody, plays a crucial role in triggering an immune response against parasitic infections. Eosinophils, a type of white blood cell, are attracted to sites of infection and release toxic substances to kill the parasites.
