Inflammatory System Of Defense Case Study

The immune system plays a vital role in helping the body to fight diseases, as well as pathogens, the disease-causing factors. It is mainly composed of the tonsils and adenoids, the lymph nodes and lymphatic vessels, the spleen, appendix, and bone marrow. The main purpose of the immune system is to assist the body in its struggle to maintain optimal health.

One defence mechanism of the human body is that when a person gets ill or is infected the person will get a fever, this is a method of notifying the person. This is a bodily defence mechanism produced by the immune system, its main purpose is to make it difficult for the virus to multiply prepare for the virus. The body’s pH level will also change to make it less optimal for the virus. The immune system’s mechanism will change depending on the body’s condition. If the body gets cut the immune system will causes inflammation, this will cause red blood cells to come to the

The body’s protection against viruses, bacteria and other types of invasions is our immune system (Tortora, 2014).

The main function of the immune system is to protect the body from infectious agents such as viruses and other toxins. The immune system can fail us in two ways-either by becoming under-vigilant, letting infections enter the body, or over-vigilant, so that it is the immune system itself, rather than an infectious agent that causes illness.

Innate Immune System – Nonspecific and abrupt first response; comprised of epithelial surfaces (physical barriers), neutrophils, and macrophages.

Human beings are born with immunity as well as they acquire it from the environment they grow in. Human innate immunity is assigned the task to hinder the harmful substances from entering the body. These immunity barriers develop a defense line. The innate immunity includes cough, tear enzymes, mucus, skin and the stomach acid. Hence, the role of innate immune system is to stop harmful materials from entering our body. In case the innate immunity is insufficient to fight, there is acquired immunity that fights harmful substances by getting exposed to various antigens. The acquired immunity is developed against specific antigen. Its role is to fight

When injury or infection occurs inflammation ensues. Inflammation is a defense response of the body that signals for the immune system to manage/fight off infection. White blood cells and macrophages are key components of this process. On a cellular level, immunity is created by exposure to foreign antigens. When the body encounters the foreign antigens it produces antibodies to destroy the antigens. B cells, a type of white blood cell, produce these antibodies. The antigen is then stored in the memory of the B cells so that when the same antigen is encountered in the future, our body can fight off the pathogen

The immune system is consisted of cells and tissues throughout the whole body. They work together to defend your body from any types of invasion and infections. Problems with the immune system can cause the immune system to mistaken the healthy body cells as invaders and will repeatedly attack the cells; this is known as an autoimmune disease. An example of this disease is the Hashimoto’s thyroiditis, where the immune systems mistakenly recognizes the thyroid cells as invaders and attack the thyroid.

The immune system consists of a defense system that guards the body against invasion from infections and other diseases. Normally, a healthy person's immune system has the capability to differentiate between its own cells and cells that represent threats to the health of the body. (Craft and Kanter, 2002). Autoimmune disease refers to a broad range of over 80 acute, long-lasting diseases that affect nearly every organ in the body. (Wrong Diagnosis.com, 2000).

The body has two immune systems: the innate immune system and the adaptive immune system.

The immune system is comprised of two responses: the adaptive immune response and the innate immune response. The first line of defence against invading organisms is classified as the innate immune response and the second line of defence and protection against re- exposure to the same pathogen is known as the adaptive immune response.

The human body is a complex system, embedded with defense mechanisms to prevent the invasion of the unknown. Not only does it protect itself from the external breaches, but also has to beware for all the potential things that can go wrong within the system. When a potential threat is detected, a trained army of cells will immediately reach the site and work towards achieving balance; this is called immunity.

Have you ever wondered how your body works? Did you ever think about how your body defends itself from outside invaders? Remember the last time you were sick. Did you know how your body fought and killed the sickness? All these questions can be answered by learning about one of the most important systems in your body, the immune system.

Our immune system is the second most complex system in our body. It is made up of organs, cells and proteins that work together to protect our bodies from harmful bacteria, viruses or other microorganisms that can cause diseases. Usually we don’t notice our immune system defending us against pathogens, but if the pathogen (harmful microorganism) is aggressive or if our body hasn’t ever come into contact with it, we can get sick. The jobs of our immune system are to recognise pathogens, as well as neutralise and remove them from our body. Our immune system also has to fight our own cells if they have changed due to an illness, for example, cancer. (1)

The immune system is a system of biological processes within an organism against the invasion from the surrounding. And different antigen is produced by different type of gene (Campbell NA, 1996).
