Dear Friends,
Welcome again to my Abode!
Whenever we get infected it is not one type of bacteria which attacks but armies of different species of them (there exist thousands of species). By the time we reach our teens our body has already encountered most of those and has devised means to destroy them. The body also keeps the experience of those encounters in the memory bank of immune system’s “hard disk” and keeps armies of counter insurgents tailormade for each type of bacteria ready to be deployed instantly. In this instance also when the body got infected through injury or consuming contaminated eatables, armies of a myriad of bacteria invaded. Only one type was a stranger, the rest were decimated in the blink of an eye when the might of specific counter forces was unleashed upon them in all its fury. The one army left unscathed was the one which the body had never encountered before in life. The body had no arrangements to launch a counter offensive as it had yet to gather intelligence about it. Left on their own this enemy started to multiply and proliferate. The toxins produced as a byproduct of their growth started making the body feel sick. A new and dangerous infection began to spread in the body. The infection started massacring the cells of the body. The dying cells sent urgent SOS through special couriers to the immune system. The body’s immune system quickly identified the threat and mobilized a full-fledged military campaign to combat the invasion.
As soon as the invading microorganisms breached the body’s defences, the immune system’s early warning systems were activated. Specialized immune cells received signals and rushed to the site of the invasion. They set up a perimeter and began to gather intelligence, assess the strength and tactics of the invading pathogens.
The brain of the immune system, serving as the command centre, received intelligence reports from all over the body and quickly recognized the severity of the situation. Orders were issued to ramp up production of antibodies, the body’s frontline soldiers. Antibodies were rapidly deployed to the frontlines to engage the enemy, marking infected cells for destruction and neutralizing the invading microorganisms.
Simultaneously, the body’s inflammatory response was activated to create a hostile environment for the invaders. Inflammation troops were sent to the infected areas, increasing blood flow and recruiting more immune cells to the battlefield.
As the battle raged on, the invading microorganisms began to adapt to the body’s defences, launching counterattacks and penetrating deeper into the body’s territory. The immune system recognized the need for specialized tailor-made forces to tackle this evolving threat.
Dendritic cells, the reconnaissance units of the immune system, scoured the battleground for information about the enemy. They captured a few soldiers of the invading microorganisms, subjected them to brutal interrogation till they spilled out desired secrets regarding their strengths and weaknesses, and raced to the lymph nodes to present their findings to the body’s decision-makers.
In the lymph nodes, the body’s leaders convened to strategize and devise a plan of attack. T cells, the elite soldiers of the immune system, were briefed on the unique characteristics of the enemy and were deployed to engage in direct combat with the invading pathogens providing these elite soldiers with appropriate arms and ammunition.
Meanwhile, the body’s production facilities worked overtime to generate more immune cells and antibodies. The bone marrow, the body’s main factory for producing immune cells, increased its output to replenish the ranks of the defending warriors lost to the enemy.
In the midst of the intense battle, some of the invading microorganisms managed to evade the body’s initial defences and infiltrated deeper into its territory. The immune system responded by triggering the release of chemicals that sounded the alarm throughout the body, alerting neighbouring cells of the danger and preparing them for battle.
At the same time, the liver, the body’s detoxification powerhouse, ramped up its efforts to clear out the toxins released by the invading microorganisms. It produced more proteins to neutralize the invaders and worked in tandem with the immune cells to contain the spread of the infection.
The invading microorganisms, however, were relentless in their assault, adapting to the body’s tactics and finding ways to evade its defences. Recognizing the need for a coordinated effort, the immune system called for reinforcements from the lymphoid organs, where specialized immune cells were being mass-produced on the basis of the intelligence gathered about the enemy to join the battle.
Back at the frontlines, the immune system launched a precision strike, unleashing cytotoxic T cells directly into the heart of the infected areas. These highly trained assassins of the immune system sought out and destroyed infected cells to prevent the spread of the infection.
As the battle continued, the body’s internal communication network, the cytokine signalling system efficiently and diligently coordinated the immune response. Cytokines acted as messengers, relaying vital information between different immune cells and directing their actions in the battle against the invading microorganisms.
Despite the relentless onslaught, the immune system remained resolute in its defence of the body. B cells, the antibody factories, churned out specialized antibodies tailored to neutralize the specific features of the invading microorganisms. These antibodies provided another line of defence, marking the invaders for destruction and inhibiting their ability to spread further.
In the heat of the battle, the body’s resources were strained, and the immune system had to prioritize its efforts to effectively combat the infection. It strategically allocated its resources, focusing on the areas of the body most heavily affected by the invasion. This prioritization also meant body was subjected to constraints and made to feel weak so as to force it to rest.
The battle reached a critical juncture as the concentrated effort of all divisions of body’s defence forces embarked upon an all-out attack on the enemy. Tide began to turn in the body’s favour. The immune system, through its sheer determination and adaptability, gained the upper hand and gradually pushed the invading microorganisms back.
As the last remnants of the invading army were cornered and neutralized, the body began the process of repairing the damage caused by the prolonged conflict. The immune system transitioned into a phase of recovery and restoration, ensuring that the body returned to a state of equilibrium.
In the aftermath of the hard-fought victory, the body’s immune system remained vigilant, monitoring for any signs of resurgence and preparing to mobilize its defences at a moment’s notice. The memory of the hard-won battle was etched into the immune system’s records, ready to inform and sharpen its response to future threats.
The body emerged from the harrowing ordeal stronger and more resilient, thanks to the unwavering dedication and prowess of its immune system. It stood as a testament to the incredible capabilities of the human body in the face of adversity, constantly adapting and evolving to safeguard its well-being against new and ever-changing threats.
A perfect military campaign with all its concomitants, wasn’t it? It involved planning, gathering intelligence, manufacturing suitable arms and ammunition and deployment and redeployment of the soldiers where they were needed the most. Was all that happening inside our bodies?
Yes! The whole series of actions was going on inside our body. This is one of the many avatars our body adopts whenever the need arises, this instance it turned into a battlefield.
Whenever the need arises?
Who or what decides when any particular action has become due or is needed?
Not you not me then what or who?
Some might argue that various “programmes” have been ingrained into us during the course of evolution. As discussed in one of my previous articles the evolution could not have happened without an intelligence to begin with. Evolution needed a blueprint to develop on the basic unit of some intelligence without which higher intelligence, that we are, could not have flourished. Our bodies dance to a well-choreographed group dance and not a free for all street dance where steps and moves of one dancer have no coordination with any other.
The programme ingrained into us is akin to a computer software construction of which follows precise rules and conditions and whose final result is a whole set of events getting performed in a precise sequence, In a definite order. I shall elaborate this aspect in one of my future articles.
Now if you say that computers now a days are capable of coding for any programme themselves even lengthy and complicated ones on their own, I would agree without doubting it, but don’t you think that computer uses it’s intelligence only when the operating system is loaded on to it’s “BRAIN” to instruct this rooted robot how to interpret the commands given to it to function. Then on top of the OS a minimum programme on how to “evolve” gets loaded to set it on it’s path to code a specific programme for itself. Tell me if I am wrong, can computer develop any software without these twin foundations, the OS and the minimum set of commands? Do these or can these programmes get coded on their own? No way! Even the smallest programmes have to be created by a skilled person only. As compared to the software loaded in this body of ours even the most intricate computer programme in existence, however complex, is like a candle compared to the blinding sun. So, didn’t the development of our programme, our evolution need some basic intelligent ingredients?
The gist of what I want to relay is that the seed for evolution of the living had to begin with the twin requirement at minimum, the OS and the initiating” software” the fundamental programme of all life to evolve on. Any software requires the services of an INTELLIGENCE to code, isn’t it? Tell me is there any other option?
The whole programme sub microscopically encoded on 4 billion molecules in our body forming one set of DNA and 33 trillion of those” programmes” forming one gigantic programme taking care of each and every cell our body every second of our life. Just imagine the enormous data populating our body …..4 billion times 33 trillion!!!!
Is this task even in the wildest imaginative capabilities of humans? Can we even think of even attempting to perform such enormities?
No way!
Can we even dare to imagine it?
No way!
If it does not belong to the realm of the capabilities of humans, then which realm would it belong to?
None else but that of the DIVINE.
We are one of the 8.7 million species which resulted from that fantastic self-evolving DIVINE computer” programme.
It is just the DIVINE, DIVINE, DIVINE all the way.
Coming back to the unbelievable military campaign that took place in our body, what was my contribution to support my “army”? Absolutely nothing!
Whenever we fall sick the medicines, we pop in do you think they are the reason for us getting well? Most of the time those medicines are just to alleviate our symptoms which are causing us discomfort, fever, pain, nausea. And whenever we are required to consume antibiotics, they are to fortify our immune system or to enervate the germs. The task of elimination of infection and disease primarily falls on our body. As shown, our body performs it with incredibly systematic way. No hit and trial, nothing at random. Each step planned and executed to perfection beyond human comprehension even. To plan such a divine programme nothing less than a DIVINE intelligence could be held responsible.
In my next edition how our body changes tactics to beat the virus which doesn’t get managed by the normal approach of our immune system to fight infection which we witnessed above.

SCIENTIFIC VERSION
The human body has an incredible defense system that fights off infections caused by various pathogens such as bacteria, viruses, fungi, and parasites. This defense system involves a complex network of cells, tissues, and organs working together to protect the body from harm.
The primary components of the body’s defense system are the immune system and the inflammatory response. When a pathogen enters the body, the immune system recognizes it as foreign and sets off a series of reactions to neutralize and eliminate the invader.
The immune system is comprised of several types of cells, including white blood cells (such as lymphocytes, neutrophils, and macrophages), which are produced in the bone marrow and circulate throughout the body via the bloodstream and lymphatic system. These white blood cells play key roles in identifying and destroying pathogens.
When a pathogen enters the body, it is first recognized by the immune system’s surveillance cells, such as macrophages and dendritic cells. These cells engulf the pathogen and break it down into smaller pieces. The broken-down pieces are then presented to other immune cells, particularly the T-cells and B-cells.
T-cells are a type of lymphocyte that plays a central role in the immune response. When a T-cell recognizes a specific antigen (a molecule present on the surface of the pathogen), it becomes activated and starts to produce proteins called
cytokines. Cytokines are signalling molecules that help coordinate the immune response by activating other immune cells and regulating their functions.
B-cells are another type of lymphocyte that produce antibodies, which are proteins specifically designed to target and neutralize pathogens. When a B-cell recognizes a specific antigen, it begins to produce antibodies that bind to the pathogen and mark it for destruction. This process is known as the humoral immune response.
In addition to the specific immune response mediated by T-cells and B-cells, the body also initiates a nonspecific response known as inflammation. When tissues are damaged or when pathogens invade, the body releases chemical signals that trigger inflammation. This causes blood vessels to dilate, leading to increased blood flow to the affected area, and causes nearby blood vessels to become more permeable, allowing immune cells to migrate out of the bloodstream and into the tissues.
As a result, immune cells, particularly neutrophils, are recruited to the site of infection, where they release chemicals and enzymes to destroy the pathogen. This process not only helps to contain the infection but also promotes tissue repair and healing.
The combined efforts of the specific immune response and the inflammatory response work together to eliminate the pathogen from the body and create a memory of the pathogen, which helps the body mount a faster and more effective response if the same pathogen is encountered in the future.
Furthermore, the immune system has memory cells, which enable it to recognize and respond more quickly and robustly to previously encountered pathogens. This is the basis of vaccination, where a controlled exposure to a harmless form of a pathogen triggers the immune system to produce memory cells, providing long-term protection against the pathogen.
Overall, the body’s defense against infections is a remarkable and intricate process involving multiple immune cells, signalling molecules, and protective responses that work together to keep us healthy and protected from harmful invaders.
