When the Immune System is OverwhelmedAlthough your body has several levels of defense and an amazing immune response, you still experience sickness. This happens when cancer or an infectious agent, such as pneumonialymphocyte(B cell)antibodyB cells proliferatesome becomememory T cellsweakened antigenon inactive virusmemory T cellsrecognizeantigensantibodiesattackantigensvirus is destroyedLATERactive virusinvades inactive virus with weakenedantigensAllergic ResponseA person with allergies has an immune system that is hypersensitive to certain materials. When the immune system reacts or overreacts to materials such as dust, pollen, latex or certain foods, we call this an allergic reaction. Exposure to these allergens produces an exaggerated response that can sometimes even threaten someone’s life.Staying Healthy and Preventing DiseaseKeeping healthy requires a combination of maintaining healthy defense systems and reducing our exposure to those materials that can make us sick. Frequent hand washing is a way to kill germs that can easily spread from person to person and reduce the risk of infection.pollendust latexglutenpeanutscleImmunization: Passive ImmunityThere are ways in which our system can be boosted or immunized to protect us from pathogens. In cases of passive immunityantibodies are injected into the bloodstream. For example, a person infected with rabies is injected with anti-rabies antibodies to acquire immunity. Another example of passive immunity happens naturally in a developing fetus as antibodies are passed from mother to fetus across the placenta. Immunization: Active ImmunityActive immunization happens when a person receives an injection of weakened antigens in the form of a vaccine. The vaccine stimulates the B and T lymphocytes, and antibodies are produced. If the immunized person is exposed to or infected with that again, the immune system is ready to defend the body against the challenge. © Copyright NewPath Learning.
