The innate defense is the body's defenses that are self-contained and fight germs. Over time, these defense-regulating genes are activated. This defense is on whether any germs enter the body or not. For example, when germs enter the bloodstream, the amount of white blood cells increases and the germs attack. When the body is cut again , the blood clots rapidly in the wound area. These happen instinctively. Again, when an unfamiliar toxin enters the body, all the defense units of the body work on their own. The brain remembers the unit that is able to distinguish. The next twenty again actually stimulates the brain and immediately activates the previous successful unit. In this way the body becomes resistant against the twenty at a time. This is called education or acquired defense. Antivenom, a snake-bite medicine, is made in this process. Most acquired defenses against the bites of various poisonous organisms.
