The Immune System
The Immune System
We are exposed to harmful microorganisms everyday, such as bacteria and virus. Many life threatening diseases are caused by pathogenic microorganisms such as pneumonia, dengue, malaria, botulism, AIDS and etc. Harmful microbes can penetrate into our body through inhalation, exposed wound, insects bites, contaminated food and water. How do our body combat of these invaders?
In most cases, our body defence system or immune system performs a great job of protecting our body from germs that cause infection and illness. The immune system is composed of a network of special cells, tissues, organs and proteins. Besides, immune system also monitors and defends the presence of any abnormal cells in the body before it develops and leads to cancer.
Disorder of the Immune System
Disorder of the immune system consists of 4 main categories:
Defined as the improper function or malfunction of immune system. A person can either born with this disorder (primary immunodeficiency) or acquires the disorder through infection or drugs (secondary immunodeficiency). AIDS is one of the life threatening immunodeficiency disease which caused by infection of a virus called HIV (Human Immunodeficiency Virus).
Autoimmune disorders defined as the inability of immune system to distinguish between substances that are "self" and those that are foreign. Thus, immune system mistakenly attack and destroy healthy tissues and organs. Examples of this disorder include rheumatoid arthritis, which the joints and surrounding tissues are inflamed.
Allergic disorders happen when the immune system becomes hypersensitive to the exposures to particular substances through inhalation, ingestion, injection or otherwise contacted. The substances that provoke such reaction are called allergens. Common allergens include pollen, animal fur, feathers, dust, dyes and certain chemical used in cosmetics. Asthma is an allergic disorder of the airway that carries air in and out of your lungs. The wall lining inside the airway becomes sore and swollen. It is sensitive and reacts strongly to allergen.
Cancer of the Immune System
This can occur when cells of the immune system grow out of control. For example, Leukemia, which involves abnormal growth of white blood cells, is a common childhood cancer.
