Immune System Fun Facts

Immune System Fun FactsWhen functioning correctly, your immune system shields against infection, disease and assists you recover after an injury. Then again, like everything, something can go incorrect and change the whole game.

The immune system is a complicated strategic fighting system powered by 5 liters of blood and lymph, a clear and colorless fluid that moves throughout the tissues of the body. Together, these two fluids transport all the various elements of the immune system so they can successfully do their jobs.

Your immune system is made up of the bone marrow, skin, spleen, thymus, antibodies, white blood cells, hormones, and more.

How Does the Immune System Work

The immune system, which is composed of special cells, tissues, proteins and organs, guards people against microorganisms and germs every single day. In most cases, the immune system does a good job of maintaining people healthy and avoiding infections. But occasionally problems with the immune system can cause infection and illness.

Your immune system makes use of a huge army of defender cells, different kinds of white blood cell. You make about 1000 million of them every single day in your bone marrow. A few of these cells, known as macrophages, continually patrol the body, destroying germs the moment they enter. This is your natural or inborn immunity. However if an infection starts to take hold, your body battles back with an even stronger defence of B- and T-cells. They give you acquired immunity, so the same germ cannot make you as sick again.

Immune System Diseases

Immune system disorders result in abnormally low activity or overactivity of the immune system. In the event of immune system overactivity, our bodies attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases reduce the body's power to fight invaders, leading to vulnerability to infections.

Allergies and Asthma

Allergies derive from the immune system's overreaction to some non-threatening foreign substance. Inhaled and foods particles such as pollen and pet dander are the most frequent allergens (substances leading to allergic reactions). Once the immune system senses an allergen, it stimulates the release of chemicals including histamine.

Asthma is a disorder where the immune system gets overactive in the airways (bronchi) in the lungs. Individuals with asthma suffer periodic episodes of constriction of their airways (bronchospasm), making it more difficult to breathe. Many people with asthma also have continuous inflammation in their airways. Asthma treatment occasionally includes a daily inhaled corticosteroid, which decreases immune system overactivity and inflammation.
