Helping the rest of the immune system, the adaptive immune system brings extra intelligence, firepower, and precision accuracy to the field of battle.
These proteins bring other immune cells to the field of battle, make neutrophils and macrophages more effective, and fight invading microbes.
It is the neutrophils that are the main defenders against infection.
In order to survive, the body needs a system that can detect and identify invaders.
Our immune system works like a military exercise where the enemy must be tracked down, identified, and destroyed.
