The human immune system is the main nerve center for protecting the body. It also maintains close defensive observations of the actions and conditions of the organ systems of the body at the cellular level. It is a system consisting of organ structures and integrating biological mechanisms that they use to identify external stimuli and prevent pathogens that are harmful to the body, infected cells or tumors. The immune system starts an attack on a foreign intruder who often sabotages and causes destruction inside the body, disrupting the activity of vital organs, attacking good cells and leaving the body vulnerable to illness or debilitating diseases.
Simply put, the immune system does not allow invaders to disrupt the human body and put it at risk.
The main goal is to protect the human body and preserve biological homeostasis among organ systems. A foreign intruder without a cause is unstable for the biological systems of the internal environment of the body and the immune system on his part is applied to being sensitive to even the slightest change that occurs deep inside the human body. The immune system is like patrolling guards, who monitor the surroundings and are ready to protect the body when a perceived threat is identified, and the type of reaction is determined regarding the nature of the intruder. When the system is warned, they build protective barricade antibodies, for example - that fight a bacterium, a virus, or even a tumor cell. This method of defensive strike is highly organized in a controlled manner, since the immune system specifically targets only foreign intruders who harm the body or infected cells that can harm other healthy cells.
The destruction of healthy cells in the body is associated with the harmful onslaught of diseases that exhaust human health and even deadly for human life. Many of these diseases, such as tuberculosis (or bacterial infection of the lungs) and AIDS (or acquired immune deficiency syndrome), are highly infectious and harm human populations throughout the epidemic. Viruses are molecular parasites that capture the human body and even mutate into several strains that can withstand the most advanced or powerful clinical drug designed to suppress them. Some viruses also cause types of cancer, for example, in the case of cervical cancer due to human papilloma infection (HPV). Cancer cells, for their part, are tricky enough to play tricks on the human body, flying under the radar of the system, so to speak, and quietly, but quickly replicating undetected ones.
The importance of the system for human life is so important and important that modern science is focused on the development of the best technologies and pharmaceutical medicine that work with the body’s natural autoimmune response, especially during a crisis.
