Bacteria , viruses , and other invaders of the system are not properly marked and so they are attacked by the cells of the immune system . This marking of one 's own cells has a genetic component such that some people respond more forcibly to pathogens while others react well to the same pathogen . Another genetic component of the immune system can operate so that some individuals have or develop immune systems whose cells do not recognize them . They can 't tell...

A cognitive analysis of behavior that is similar to resistance yields a deeper understanding of how people transform and learn and presents greater opportunities for productive technology deployment .

Hans Seyle , who discovered three stages of a human organism 's reaction on stress and called it General Adaptation Syndrome . These stages include : alarm phase , when the body gets ready for possible dangerous reactions , resistance (or adaptation ) phase , when the body is getting used to the stressors and tries to decrease irritation , caused by the stressors , and exhaustion phase , when the body runs out of the resources , like immunity or energy , and falls into exhaustion .

See ``Journal of Antimicrobial Chemotherapy . Antibiotics , depresses the immune system and takes over its job . A depressed immune system causes secondary infections to become more deadly . As already mentioned , antibiotics cannot detect the good from the bad bacteria . Hence , the ``good ' bacteria (probiotics ) needed for cleansing toxins from the body is depleted as well . A naturally created hormone in the body , called corticosteroids , has been administered in abundance because of its anti-inflammatory properties . The use of corticosteroids is a double...

HIV comes from the family of viruses called `retroviruses ' that have unique ability to copy RNA into DNA . The virus has two congruent copies of RNA as its genome surrounded by spherical core of protein . The virus gets itself with on the T cells which sort of engulf it and result into dissolution of protein core and thus leaving RNA exposed and an enzyme `reverse transcriptase ' starts making copy of RNA into DNA . The DNA strand thus produced also undergoes...

O2 which is together associated by the respiratory system . All organisms despite their conformation they all possess an organ system which is a coordinated living whole that is greater than the specific parts that bring about the organ systems .
