Immune System
What is immune system?
The immune system is that composite operation within our bodies that keeps us health and disease-free. Few systems in nature are as changed as the human immune system. It lives apart from, and works in concert with, every other system in the body. The main element of the immune system is the lymphatic system. Small organs called lymph nodes help carry lymph fluid throughout the body. This is why an aroused white blood cell count is often an indication of infection. The worse the infection, the more white blood cells the body sends out to fight it.
Vaccines are vital in helping the body avoid certain illnesses. The body is injected with a decreased or dead form of the virus or bacteria and develops the allow antibodies, giving complete activity against the full-strength form of the disease. This is the reason such disorders as diphtheria, mumps, tetanus and pertussis are so rarely seen today. Children have been vaccinated against them, and the immune system is on the alert. Vaccines have also been instrumental in eradicating plagues such as smallpox and polio.
