Fundamentals of the Human Body Immunity System (PDF)

Scientific Essay from the year 2013 in the subject Health - Public Health, grade: A, ( Atlantic International University ) (Social Studies and Humanities), course: Public Health Immunology, language: English, abstract: In so many cases, we have been accustomed to the phrase "prevention is better than cure" yet in so many cases, we find ourselves victims of disease that in so many instances, we are not sure how we came to contract them but instead we embark on treatment after which we forget knowing about them.
It does not require extensive knowledge to realize that our body systems have inbuilt immune mechanisms by which humans survive the prevalent infections caused by the common bacteria located in almost every environment of man's involvement. The fact of immunity is not an artificial health aspect built on man's innovations in science but rather a natural fundamental of human life and therefore this provides the basis of preventive health and immunization.
Body immunity refers to the process or phenomenon through or by which the living body system is capable of identifying, isolating the foreign intruding harmful microorganisms and destroy or disarm them of the toxins that would be hazardous to the normal functioning of the body. The ability of the body to activate immunity against harmful microbes determines the health status of an individual and this is the foundation of immunology which is a perspective study directed against infectious disease spread in human communities.
Immunology, which is a basic subject in medical sciences, finds its purpose along with microbiology, infectious disease control. In consortium with these medical subjects, immunology is regarded as the study of the fundamental physiological body components (molecules, tissues, cells, organs and systems) that are responsible of isolating foreign harmful bodies and disposing them out. The significance of immunology in the health science world is that it explores the common trends of disease emergence with an intention not of epidemiological importance but far more to devise vaccination, which can is applicable to prevent it from continuity.
Through this conceptual and systematic study of immunology, the fundamental constituents of human immunity system, their functional pathways, regeneration, and replacement are analyzed. The study paper also entails the significance of immunology in the public health strategies of reducing health inequalities and disparities in the international community through international conventions on health policy structuring such as immunization are idealized.
