Immune system

allergies pets may experience are food allergies and environmental allergies. As a general rule of thumb, seasonal allergies are situated within the “environmental” category of allergies. Allergies of any type are an overreaction of the immune system, in which the immune system identifies the allergen as a foreign substance that it must eliminate. As the animal’s body tries to fight this substance, the reactions in the form of allergy symptoms occur. Several different…

It is the only hepatitis virus with a DNA as its nucleic acid. The HBV interferes with the functions of the liver by replicating in hepatocytes, by which the host’s immune response causes hepatocellular damage in attempt to rid of the virus. (Further explained in Host Response) The surface antigen HBsAg is in the envelope and its presence in blood indicates an active infection. Another antigen HBcAg, is a core antigen…

of age are mainly infected with this disease. The color of the ribbon for aids is red. Aids is a disease that makes your immune system weak. It destroys a specific type of cell that is important to your immune system called CD4. CD4 cells are a type of white blood cell. CD4 cells trigger the body's response to infections. If these cells are destroyed ,then the immune system can not fight back and defeat the infections. The disease can be transmitted through needles or syringes that have…

diseases, and research shows that they have been successful in doing so. This success, however, depends on herd immunity. Herd immunity is when the majority of a group or herd are immune to a particular disease or virus and that disease or virus is unable to spread and consequently dies. Not everyone in the group is immune, but because the majority of…

eliminate diseases. Because of these reasons, I would like to encourage the members of the community to be sure they are properly vaccinated. A vaccine is a preparation of dead or weakened pathogens that are introduced into the body to stimulate an immune response. Medical professionals administrate vaccines as an oral spray, or nasal spray, but usually as an injection. One of the reason that vaccines are important is because they protect you from disease. How…

different interactions among the nervous, endocrine, and immune systems (Ader). During a stressful event, the body may undergo a series of biological and chemical changes. For example, the sympathetic nervous system and hypothalamic pituitary adrenal axis system are activated and hormones are released (lecture). This promotes the process of turning fats into energy for the body to use and therefore, this energy, which could be used in other systems and activities in the body, is not available…

prevention of disease in the immune system. More specifically, they target T-helper cells, which are a type of lymphocyte. The T-helper cells act to produce and release cytokines, which stimulate various immune responses e.g. interleukins trigger B lymphocytes to differentiate into plasma cells which produce antibodies that are crucial in fighting disease. When the numbers of these T-helper cells fall below that needed to successfully destroy pathogens, the ability of the immune system to fight…

is the high price of cigarettes. They contain a nasty chemical, and that chemical is called nicotine. On top of all of that, cigarettes weaken a human 's immune system. Cigarettes are dangerous to any and all users. As if a person did not already know, smoking destroys your lungs like an atomic bomb. Smoking can cause the body’s immune system to attack lung tissue and result in severe respiratory disorders. After smoking for a long enough time, your lungs will no longer be able to filter…

of the immune system against unwanted antigens. When a shot is applied to the patient, his or her body is introduced to weaken or killed germs of a certain type of infection (Medicinenet). The introduction triggers the immune system to create the necessary antibodies in order to attack the invader. As mentioned in Medicinenet, the antibodies will remain in the body and provide protection against the actual malady. As the amount of antibodies accumulates, the stronger the child’s immune system…

(DMARD), used to lessen swelling and slow progression by targeting the immune system. The immune system may be weakened due to the use of a DMARD. Biologic response modifiers are used alongside DMARDs drugs. Biologics modify the immune system by blocking TNF, the underlying cause of inflammation. This helps stop further joint damage and makes everyday tasks easier. Unfortunately a side effect is having a weaker immune system, making it easier for users to catch viruses. Biologics must be…
