WHAT IS IMMUNE SYSTEM ?

The immune system protects our body from the harm substances unacceptable to our body. Immune system includes germs such as bacteria, fungi , viruses, and some chemical made by microbes called toxins. 

There are 2 main parts of the immune system:

• The innate immune system. 
• The adaptive immune system.

These 2 immune systems work together.

Immune system makes the special protein with the help of innate system called antibodies. Antibodies are produced against antigens or pathogens to protect our body from infections. The immune system are made in different organs of our body in which it includes:

• Adenoids. Two glands located at the back of the nasal passage.
• Bone marrow. The soft, spongy tissue found in bone cavities.
• Lymph nodes. Small organs shaped like beans, which are located all over the body and connect via the lymphatic vessels.
• Lymphatic vessels. A network of channels all over the body that carries lymphocytes to the lymphoid organs and bloodstream.
• Peyer patches. Lymphoid tissue in the small intestine.
• Spleen. A fist-sized organ located in the belly (abdominal) cavity.
• Thymus. Two lobes that join in front of the windpipe (trachea) behind the breastbone.

The immune system has a key role that it protects our body from germs , harmful substances and cell changes that could make you ill. Various organs ,cells and proteins together form a immune system. 

The immune system is a network of biological processes that protects an organism from diseases. The immune system can be operated through lot of  different materials that the body does not admit as its own. These substances are known as antigens. Some examples of antigens including the proteins on the surface of bacteria, viruses and fungi. There are two main sub components in the immune system, known as the non - specific or innate immune system and the specific or adaptive immune system. Both of these subsystems works  and closely linked together whenever a harmful substances or a germ set off an immune response. The main function of the immune system is to prevent or limit infection.
