The human immune system is the body’s basic nerve centre of defense. Additionally, it keeps a close protective watch over the actions and states of the body’s organ systems at the cellular level. It’s a system comprised by organ structures as well as the integrative biological mechanisms that they use to be able to recognize external stimuli and stop -agenți patogeni amenințători, țesuturi infectate sau tumori să nu dăuneze organismului.

Sistemul imunitar

The immune system launches an attack on a foreign intruder that often sabotage and lead to destruction within the body-disrupting the actions of the crucial organs, assaulting good cells and leaving the body vulnerable to illness or debilitating ailments. To put it simply, the immune system prevents germs from bothering the and placing it in peril. The principal is to safeguard the human body and preserve biological homeostasis among the organ systems.

Un intrus străin din afara instabilității fără cauză în sistemele biologice ale mediului intern al organismului, iar sistemul imunitar, datorită rolului său, este pregătit să fie sensibil la cea mai mică schimbare care are loc în interiorul corpului uman. Sistemul imunitar sunt asemănătoare unor paznici de patrulare care supraveghează zona și sunt pregătiți să apere organismul atunci când se identifică o amenințare percepută și se stabilește tipul de reacție în raport cu caracterul intrusului invadator.

E bine de știut

Atunci când sistemul este alertat, acestea construiesc o baricadă defensivă - anticorpi, de exemplu - care luptă împotriva bacteriei, sau doar o celulă tumorală. Acest mod de atac defensiv este foarte bine organizat și controlat, deoarece sistemul imunitar vizează în mod specific doar insectele străine care vor să facă rău organismului sau celulele infectate care pot afecta alte celule sănătoase.

The destruction of healthy cells in the body is connected to the devastating onslaught of diseases which are debilitating to human as well as deadly to human life. Many of these illnesses like tuberculosis (or bacterial of the lungs) and AIDS (or Acquired Immune deficiency Syndrome) are highly infectious and wreak havoc to human populations at epidemic proportions.

Concluzie

Viruses are molecular parasites that take over the human body and even mutate into several breeds which could withstand the most advanced or strong clinical designed to quell them. Some viruses additionally cause kinds of cancers such as in the case of cervical cancer as a result of Human Papillomavirus (HPV) infection. Cancerous cells, for their part, are wily enough to play tricks on the human body by flying under the system’s radar so to speak and softly yet quickly replicating undetected.
