The human immune system will be the body's fundamental nerve center of defense. It also keeps a close protective watch over the activities and conditions of the body's organ systems at the cellular level. It can be a system constituted by organ structures as well as the integrative biological mechanisms that they employ so that you can identify external stimuli and stop life-threatening pathogens, infected cells, or tumors from harming the body. The immune system launches an attack on a foreign intruder that often sabotage and trigger destruction inside the body-disrupting the activities of the vital organs, attacking great cells and leaving the body vulnerable to sickness or debilitating ailments.
Just put, the immune system prevents invaders from disturbing the human body and putting it in peril.
The primary aim would be to protect the human body and preserve biological homeostasis among the organ systems. A foreign intruder from without having trigger instability to the biological systems of the body's internal environment as well as the immune system for its part is primed to be sensitive to even the slightest alter happening deep inside the human body. The immune system are like patrolling watchmen that keep an eye on the vicinity and are prepared to defend the body when a perceived threat is identified and the type of response relative to the nature of the invading intruder is determined. When the system is alerted, they build a defensive barricade-antibodies, for example-that combat a bacterium, virus or even a tumor cell. This mode of defensive strike is highly organized in a controlled way for the immune system specifically targets only alien intruders that mean harm to the body or infected cells that will harm other healthy cells.
The destruction of healthy cells in the body is linked to the disastrous onslaught of diseases that are debilitating to human wellness and even fatal to human life. Several of these illnesses such as tuberculosis (or bacterial infection of the lungs) and AIDS (or Acquired Immune deficiency Syndrome) are highly infectious and wreak havoc to human populations at epidemic proportions. Viruses are molecular parasites that take over the human body and even mutate into several strains that will withstand essentially the most advanced or effective clinical drug developed to quell them. Some viruses furthermore trigger forms of cancers including in the case of cervical cancer because of Human Papillomavirus (HPV) infection. Cancerous cells, for their part, are wily sufficient to play tricks on the human body by flying under the system's radar so to speak and quietly however quickly replicating undetected.
The system's significance to human life is so essential and critical that contemporary science is driven to develop the very best technology and pharmaceutical medicine that function with the natural autoimmune response of the body especially in times of crisis.
