You have probably heard of our immune system. But, how much do you actually know about it?
Well, there is a great reason to find it out. You really need to understand what it does for your body and why you should keep it well-functional.
The human body is always at the risk of getting affected by nasty germs and microbes.
Microbes or tiny organisms like parasites, virus, fungi, and bacteria can cause harmful and painful infections to the human body.
And, the immune system defends or safeguards your body against these “foreign invaders” (microbes).
The immune system is made up of proteins, tissues, organs, and special cells that safeguards people against microorganisms and germs every day. In this way, the immune system protects your body from harmful influences of the environment (like a guardian).
And, it is utmost essential for survival.
For example, when you catch a cold virus, the immune system targets the virus and defends your body against it.
Sometimes, you may need to undertake some medicines for a quick remedy. However, the immune system is the basic cornerstone of germ prevention and recovery.
Unfortunately, your body offers a perfect environment for many microbes to grow.
And, it’s the responsibility of the immune system to constantly seek out and destroy those microbes.
But, if the immune system mistakenly hits a wrong target, it can lead to a plethora of diseases.
Among immune system-related diseases, asthma, diabetes, and allergic diseases are quite common.
Note, the internal structure of your immune system is extremely complex.
And, it has the inherent capability to recognize and remember heaps of foreign invaders.
Furthermore, it produces secretions (a special type of body fluid) and cells that can wipe out most of them.
The secret to its success (i.e. detecting and defending the germ/microbes) depends on its dynamic communications network.
This elaborate communications network comprises of millions of cells.
These cells are organized into various sets and subsets.
When one of the cells of your immune system receives or notices the alarm, it becomes activated and begins to produce powerful, chemical body fluids.
While these cells regulate the growth and behavior of a certain microbe, they can even enlist other immune system cells and direct them to detect and defend the attacks.
Scientists have already conducted rigorous research in order to understand how human body (specifically the immune system) launches reverse-attacks in order to destroy unwanted foreign invaders, tumors, and infected cells (while ignoring the healthy tissues).
With the advancement of technology, scientists are now able to quickly determine how an individual immune cell targets a microbe by triggering an immune response.
Please note, your immune system consists of five major components, for example, Lymph nodes, Spleen, Bone marrow, Lymphocytes, and Thymus.
Latest technological advancements of microscopy have permitted the scientists to observe T cells and living B cells as they interact with body tissues and lymph nodes.
In addition, scientists are also researching about the biology of viruses, bacteria, and parasites.
Combining the expanded genetic information and latest technology, we will soon get to know how our body protects itself from various diseases (in a more detailed and accurate way).
