How the immune system works.The defense mechanism of your body is made up of antibodies. Also known as immunoglobulins, the antibodies are Y-shaped proteins which identify and remove abnormal or foreign antigens such as the virus and the bacteria. Each antibody detects a specific foreign cell by the use of its Y tips. The two ends of an antibody are specific to one antigen which allows various antibodies to bind to a wide range of foreign cells. The antibodies are produced in response to foreign cells detected in the body. Through the raised production of antigens when fighting against common illnesses like a cold or the flu, the body can protect itself from major illnesses like heart disease or even cancer. Other than the antibodies, the body defense may also respond to an attack by using the cell-mediated immune system. This is where your body through the help of the immune system cells creates memories of the past defenses against specific threats. When the immune system recognizes the foreign substances from a past invasion, it calls on the memory and destroys the threat before the disease gets a chance to mutate and become harder to fight. Vaccines and immunizations use this mechanism where they contain small and harmless amounts of the disease. The shot helps to trigger the body’s memory where your immune cells react by raising defense against the infection and destroying it.
Ways of maintaining your immune systemYou may be lowering your immune system through myriad ways without knowing and which can be dangerous. This is because it makes you susceptible to any form of attack, even the most common like the cold. Most of them are bad health habits that can be easily avoided. They include;
- Sleeping for less than seven hours
- High levels of stress
- Poor hygiene habits
- Lack of exercise or too much exercise
