Research into the effects of stress on the immune system There have been various studies into the effects of stress on the immune system. Kiecolt-Glaser researches this by looking at how quickly wounds heal. She used 13 women aged 47-81 who cared for Alzheimer’s and Dementia sufferers. They had naturally occurring high stress levels‚ and this is why she chose them. The women were matched with volunteers for maximum similarity (the matched pairs design). Kiecolt-Glaser tested all the women’s

It works against a specific disease by training the immune system to rapidly recognize and eliminate the infectious agent that causes that disease‚ thus resulting in immunity. Protection can be acquired either by passive or by active immunization.Passive immunization involves transfer of antibodies obtained from an immune donor to a nonimmune individual and results in temporary immunity. Currently‚ antibody-based therapies represent a

Adaptive (specific) defense system The immune system is a functional system rather than structural; there are no specific immune system organs Pathogen: a disease-causing agent; anything foreign in our body that causes disease Three lines of defense: 1st: external barriers 2nd: several non-specific defense mechanisms 3rd: immunity‚ specific resistance to disease

disease itself is caused a bacillus called Mycobacterium tuberculosis and mainly affects the lungs‚ however the central nervous system‚ the lymphatic system‚ the circulatory system‚ the genitourinary system‚ bones‚ joints and even the skin also has a chance of being affected. Our body’s immune system responds to this infectious disease by having a group of white blood cells to try to identify the disease causing bacterium and destroy it. Another way our body responds to this disease is to attempt to digest
