Your immune system protects you from diseases and illnesses. The immune system functions like a burglar alarm that attacks dangerous invaders before they enter the home. It scans for dangerous pathogens on the surface of your body, the bottom of your feet, and under your skin. When it detects an enemy, it alerts your immune system to fight or flee.
Your immune system constantly works to prevent you from diseases or infections. Its job is usually to either kill off or to limit the extent of the damage done by foreign organisms when they enter or if they get inside your body. Your immune system recognizes various microorganisms once you have been exposed to them as well.
Your body can develop both innate and adaptive immunity. Some people are more susceptible to pathogens than others. This means that they have a greater risk of developing illnesses that can be harmful. These include: viral, bacterial, and parasitic infections.
There are diseases that strike at various ages and can affect any part of the body. Some of these age-old diseases include: chronic arthritis, psoriasis, measles, influenza, syphilis, and multiple sclerosis. All these diseases have symptoms similar to those of autoimmune diseases. Some of the symptoms of immune system disorders include: swelling, redness, pain, fever, diarrhea, constipation, and loss of appetite. Some individuals are predisposed to getting such diseases while others do not have such a predisposition.
Many autoimmune diseases are caused by foreign organisms that enter the body through the skin or gastrointestinal tract. They then cause inflammation, which results in pain, swelling, and other changes that damage the tissue. Such organisms can also be transmitted by direct contact.
Autoimmune diseases occur when the immune system is unable to fight off infections. The most common way this occurs is when a person’s immune system is lacking some of the protective chemicals or antibodies that it requires in order to fight infection. In order to compensate for a lack of these substances, a person will produce antibodies against their own tissues and cells. However, this process is not natural. When the body is unable to recognize an illness, then it will try to fight off the infection using the antibodies. This is the reason why people who take antibiotics often experience recurring infections.
Some researchers call adaptive immunity innate immunity. They believe that we are able to naturally strengthen our immune system by exposing our bodies to germs that are potentially harmful. For example, when we are sick with a cough, we may touch our mouth or nose and inhale particles of dust. Some scientists theorize that this action causes a build up of mucus that protects our lungs from germs. This same theory could explain why people who are exposed to mold or fungus develop an allergic reaction to it.
When the body is exposed to germs that cause infection, it creates antibodies called antigens. Antigens are substances that bind to the pathogens (allergens) after they are introduced to the body. These antigens help the body recognize and fight them. Antigens are substances that should be produced by the body if it is unable to fight off disease. Common examples of such substances include IgE, lymphocytes, T-cells, and mast cells.
The body also has white blood cells called white blood cells, which work to kill off any foreign organisms that might cause illness. The white blood cells help to regulate the immune system. The function of white blood cells is to produce antibodies and release substances called leukotriene modifiers. The leukotriene modifiers may interfere with the production of allergic reactions and other immune system disorders like eczema. Some researchers think that some children with allergies may not get sick unless they have these modifications in their immune system.
Our immune system protects us from diseases and infection by fighting against bacteria and viruses. Some bacteria and viruses are part of our healthy flora. If the healthy flora is destroyed, infections can then take place. Some infections can be transferred through breathing and touching. It is essential that if you are prone to colds and flu, you should get regular checkups so that your body’s defenses are always strong.
Our bodies can fight off germs and viruses but it takes time for them to do so. Our immune system can fight off certain illnesses, but not all infections are curable. If you think you have an illness, you should consult a doctor immediately. The earlier you catch an illness, the sooner you can treat it and recover from it.
