Immune System Function

We have often heard that in ancient times, kings and soldiers used to wear amours that acted like a protective covering for the chest. It was commonly used during sword fighting. These armors shielded the chest against sword or dagger attacks. The way the armor served as protection, similarly, the immune system works to keep the body protected against harmful micro-organisms.

What is an Immune System?

It is a natural defense mechanism developed in our body that helps to maintain overall health. It is made up of tissues, lymph nodes and cells, and is primarily designed to kill infection causing organisms. Proper functioning of the immune system is essential to keep health in good shape. When the immune system does not work, the person becomes susceptible to infections. Problems with the immune system, often manifests in the form of illnesses that occur frequently. In other words, an impaired immune system, makes a person sick and is no longer capable to keep the person healthy.

Kill Invaders Harmful to Health
The immune system thwarts off various viral and bacterial invasion. Consider this: United States has one of the largest military force, which is very much capable to successfully defend any kind of enemy attack. Similarly, a strong immune system, won't allow the pathogens (bacteria, virus) to spread the diseases in the body.

Production of White Blood Cells
The major function of our defense mechanism is to produce white blood cells, which are referred to as soldiers of the body. They help to destroy foreign invaders (pathogens), in turn maintaining health. Also known as the immune system's army, these cells play a crucial role to protect the body against infections. These cells are an integral part of the immune system that detects the presence of foreign particles and does not allow them to gain control over the body.

Identification of Pathogens
Before actually killing bacteria, it should be able to distinguish between 'good' and 'bad' bacteria, otherwise, it may end up destroying its own body tissues. This job of differentiating foreign particles is also effectively executed by the immune system. It is crucial for complete destruction of pathogens.

Notifies Entry of Pathogens
Fever, or inflammation are regarded as the immune system's response to infection. This is how our defense mechanism works. When pathogens travel inside the respiratory tract, the immune system reacts by producing a dry cough, so as to expel them. Thus, our defense mechanism notifies that there is something wrong in the body, indicating use of prescription medicines to eradicate the pathogens.

On the whole, optimal functioning of the immune system is very important for greater longevity and better health. A decrease in immunity will surely affect the health. The key to maintain a healthy immune system is to have a nutritious diet and stay away from unhygienic habits like excessive drinking, smoking or tobacco consumption.
