How Your Immune System Protects You from Disease

To defeat an enemy, you must be ready to give it your all. Of course, an enemy must be secretly fought before it actually comes to the battlefield or else, a failure to do so will bring a greater probability of losing. Same concept is applied in our bodies. We hide a secret defense mechanism to protect us from unknown enemies that may probably enter our borders at times when we least expect it. That defense mechanism is our immune system.

Immune System- Your ardent defenders…Behind the Scenes with your Immune System

The immune system is composed of an intricate group of tissues, organs, and cells: the lymph nodes, spleen, bone marrow, thymus gland, tonsils, white blood cells, antibodies, and interferon. The parts that comprise the immune system work as a team to keep one’s body strong and healthy. These parts have specific functions and manners to correspond to each other.

The most vital role of the immune system is its defensive responsibility in the human body. The immune system has an intrinsic capacity to identify and confront foreign substances and organisms within the body that may potentially be causes of disease. The disease-causing bacteria are referred to as pathogens. Therefore, the system acts as the critical primary line of security. The immune system performs a role in eradicating destructive organisms and substances by detecting, annihilating, and lastly wiping out different kinds of foreign particles in the human system. It is consequently an absolutely independent and imperceptible shield, running unobserved in our bodies and carrying consideration to itself whenever we get sick. Otherwise, we are oblivious of its existence. All pathogens discharge certain chemicals and proteins that our immune defense recognizes. Recognition activates a kill reaction. As a matter of fact, the cells in the immune system that are accountable for killing actually consume and digest the pathogen. Eating the pathogen permits some of the killer cells to package the pathogens so that the other constituents of the immune team will recognize them if the same so called “invaders” return.

3d key At instances when an invader returns, the team members in charge for detecting past invasions notice the invader’s chemical signals. This signal fuels them to produce and emit chemical tags called antibodies. These antibodies attach to the invaders and allow the killer cells to be familiar with that invader and kill it again. Cells whose obligation is to guard and report do a different structure of recognition. From time to time invaders can be successful and make their victim cells sick from the inside. When this happens, the victim cells request assistance by showing proteins on their exterior parts that serve as an alarm clock. Once this alarm clock rings, the guarding team instantly hears the sound and does their function immediately. The team kills the infected cells and announces to the other immune cells that there is an invader in the area that has to be abolished. Therefore, the invaders in the interior of the infected cells are devastated and the invaders that are still planning to infect are killed before they do a single step.

A battle is won according to how well it is fought. In the case of our body, it battles along with the immune system to prevent its team, all other body parts, from being entered by an enemy’s force.
