Human Body And The Immune System - 952 Words

The Fundamentals: When a person is sick, their first course of action is usually to take medication. While medication can aid in sickness, the human body is actually built to naturally defend itself using the immune system. The immune system is comprised of biological structures and processes that protect the body from pathogens which cause disease or sickness. As much as the immune system does to protect us, it is the chief hurdle of transplantation of living cells from one organism to another. The immune system recognizes anything foreign put into the body as a threat that must be removed. Consequently, transplanted tissue or organs meant to save a life are often attacked and rejected by the recipient’s body. The immune system is a hodgepodge of different structures and pathways that work together as a unit. It recognizes foreign objects that enter the body through antigens. Apart from identical twins, no two people contain the exact same antigens [Adams 2011]. Once foreign antigens are noticed by the immune system antigen receptors, T cells and B cells, it begins creating antibodies. Antibodies are also called immunoglobulins and are proteins produced by white blood cells, which locate the antigens on the surface of the foreign object and either neutralizes the threat directly or tags the antigen to be destroyed by other immune system agents. Allotransplanting is the process of transplanting living cells, tissues, or organs from one human being to another. This processShow MoreRelatedThe Immune System Of The Human Body1257 Words   |  6 Pages Immune System Monica Salazar BIO1021 Dr. Kimberly Snead McDaniel South University Online We are examining the role the immune system plays within the general day to day operation of the human body.

The body can reject the transplanted organ; as a result the body’s immune system will not accept the organ which has been transplanted; therefore it can have an effect on the organ that has been transplanted which is possible. The immunosuppressant drug is needed if the organ does reject the human body; the immunosuppressant drugs acts as an anti-rejection drug which is needed to protect the body from the organ that has been transplanted to reduce theRead MoreThe Human Body S ystem Is Not Immune For Pathological Deficiencies1827 Words   |  8 PagesOur body system is not immune to pathological deficiencies. There exist numerous identified pathologies which compromise the regular functioning of a heart, but all heart-related pathologies are narrowed to a single condition known as Acute Coronary Syndrome (ACS). This is the term formally used in reference to the different identified clinical entities threatening the cardiovascular system. ACS is the result of the progressive or complete sudden blocking of the arteries or veins; this prevents anRead MoreAntibiotic Resistance And Its Effects On The Human Body s Immune System Essay1295 Words   |  6 PagesAntibiotics are derived from microbes that work by inhibiting the growth or by killing other bacteria (Tortora, Funke, and Case 549). Usually our body’s immune system is an ample defense by stopping microbes from replicating or killing them. However, sometimes the body can become overwhelmed and th at is when antibiotics are used to help out our immune systems. An important dilemma in medicine is the increasing occurrence of antibiotic resistance, which occurs when bacteria are exposed to the same antibioticsRead MoreThe Human Immune System Is A Complex Defence Mechanism That Protects The Body From Harmful Pathogens Essay1486 Words   |  6 PagesThe human immune system is a complex defence mechanism that protects the body from harmful pathogens. Our innate immunity provides humans with a thorough degree of protection, but epidemics are still common throughout the world. To give an example of scale, over 14 million people die annually from vaccine-preventable diseases. In New Zealand a majority of diseases have been eradicated, but some such as whooping cough and pneumococcal are still present. To reduce and stabilize the amount of casesRead MoreDifferent Systems in a Human Body Essay1018 Words   |  5 PagesHuman Body System Interaction . All the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive.

Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin. White blood cells are part of the immune system and help defend the body from antigens. Innate Immunity The innate immune system is effective to a certain degree.

Why in a hundred billion years of evolution would we evolve a response for allergy?†(Joel Weinstock). Throughout the years, food allergies have been on a dramatic increase in the United States. Allergic reactions are caused by antibodies in the immune system which are also known as immunoglobulins. There are five types of immunoglobulins that are produced to fight antigens, such as, bacteria, toxins, viruses, animal dander, fungus, and cancer cells .
