Question

What are the advantages of a specific defense?

Answer 1

Monocyte/macrophages are two non-specific immune defenses. If you had no skin it would be pretty tough to roll around in the mud without getting an infection. Also, without the WBCs chillin in there to catch anything that happened to break through you would get an infection every time you get a paper cut. 

Answer 2

Fevers may also slow down the reproduction of some bacteria and viruses. Whether the mechanism is as complex as fever and inflammation or as simple as physical barriers and phagocytosis, all nonspecific defenses provide the body with general protection against foreign invaders.
