Best Answer

Physical barriers like skin and mucus membrane protects body from invasion of microorganisms. If they happen to cross these barriers, then 'innate immunity' of body kills the bacteria. If they happen to be pathogenic bacteria, then white blood cells go there and engulf them. They are helped by 'humeral' immunity of body. Thensubsequently immunity comes into action by 2 weeks to defend further attack by the same organism.
