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

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

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 progresses to AIDS at a variable rate affected by viral‚ host‚ and environmental factors; HIV-specific treatment delays
