that life stress and negative emotions may affect our immune systems adversely. However‚ one limitation of the study is that it only shows a correlation and not the cause. As Cohen didn’t directly cause the participants stress‚ it isn’t possible to determine whether high levels of stress actually do affect the functioning of the immune system negatively. It is possible that those who didn’t contract a cold may’ve had stronger immune systems than those who did and as a result‚ individual differences

Case Study: Tuberculosis 1) What is Tuberculosis? Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. It mainly affects the respiratory system by mainly damaging and destroying lung tissue but can affect other parts of the body. It also suppresses the immune system making the body less able to fight any disease. 90% of people who are infected develop latent TB‚ which is were the bacteria are present in the body but are not active. This means the people

Tak 1.1 List all the systems of the human body with their functions and major organs. The circulatory system is the body’s transport system. It is made up of a group of organs that transport blood throughout the body. The heart pumps the blood and the arteries and veins transport it. Oxygen-rich blood leaves the left side of the heart and enters the biggest artery‚ called the aorta. The aorta branches into smaller arteries‚ which then branch into even smaller vessels that travel all over the

From Celiac Disease to general distaste‚ gluten-free diets are on the rise and it may seem to some that the appearance and prevalence of gluten-sensitivity is a modern phenomenon‚ cashing in on a Western trend without a real scientific base. It may surprise the cautious reader to discover that Celiac Disease is in fact one of the most common long-term diseases worldwide with a history likely dating back to at least the first and second centuries. This begs the question: what is celiac disease? Where

About Vaccines Vaccines work by stimulating our immune system to produce antibodies without actually infecting us with the disease. Antibodies are substances produced by the body to fight disease. Vaccines generate the immune system to produce its own antibodies against disease‚ as though the body has been infected with it. This is called "active immunity". If the vaccinated person then comes into contact with the disease itself‚ their immune system will recognise it and immediately produce the antibodies

HIV infection is a disease caused by the human immunodeficiency virus (HIV). The condition gradually destroys the immune system‚ which makes it harder for the body to fight infections. Most people infected with HIV eventually develop AIDS. These individuals mostly die from opportunistic infections or malignancies associated with the progressive failure of the immune system. HIV progresses to AIDS at a variable rate affected by viral‚ host‚ and environmental factors; HIV-specific treatment delays

This research suggests that reintroducing some of the organisms from the mud and water of our natural world would help avoid an overreaction of an otherwise healthy immune response that results in such chronic diseases as Type 1 diabetes‚ inflammatory bowel disease‚ multiple sclerosis and a host of allergic disorders.
