A Bad Day!
What really happens when you have a fever.
How It Happens
At the base of the brain the hypothalamus acts as a thermostat. While the pathogens are producing pyrogens, the hypothalamus detects them and the body begins producing heat. The pathogen in the fever would be both viral and bacterial. Antibodies are produced by white blood cells and they are apart of a specific immune response to foreign matters. The immune system recognizes the pathogens in two ways. First, the white blood cells attacks the pathogens and produce chemicals that help the other white blood cells. Second, the white blood cells produce antibodies specific to reach pathogens and provide the body with immunity.
A type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles.
A bacterium, virus, or other microorganism that can cause disease.
A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
Sine the pathogen got through the first defense, what happens with the second defense? Well, the second line of defense is the inflammation response. In other words, the swelling, redness, and heat are signs that the pathogens got through the first defense. Most pathogens can't tolerate heat, so they grow weak. The pathogens affects more than one area of the body. This causes a temperature rise, but it mostly damages most of the tissues. When you try and lower a high fever, medication is advisable in order to avoid tissue damage.
A specific immune response differs from nonspecific immune response because a specific immune response triggers antigens. When the body detects a foreign antigen, specific immune responses occur. Secondly, a specific immune response provides protection from future exposures to the same material. When the T cells divide, B cells recognize the foreign antigen. After a few days, B cells begin to produce antibodies that help destory pathogens. In the future, if the same pathogen enters the body again, the body will be able to respond more quickly.
