AS Psychology Unit 2: Stress-illness and The Immune System Notes The immune system refers to the mechanism in the body that provides a defence against infections‚ e.g. bacteria‚ viruses‚ parasites and toxins. The immune system fights off invaders that cause disease (antigens). The cells in the system are leukocytes (white blood cells) called phagocytes and lymphocytes. Phagocytes are the first line of defence‚ providing a general barrier against antigens. Leukocytes are more focused and are

this happens‚ it is known as an infection which in turn make people ill. Our body uses its immune system to fight of the infection that has began spreading in the body. Vaccines are used to help our immune system develop an immunity by imitating the infection. This means that there is a small amount of the bacteria or virus introduced to the body but it does not make the person ill. This causes the immune system to create t-lymphocyttes and b-lymphocytes‚ white blood cells that attack cells that have
