    complexity of the human immune system comprises of specialised cells(leukocytes), proteins (antibodies, lysozymes), tissues (lymphatic vessels), and organs (spleen) working together to fight off pathogens due to constant exposure. The first line of defence is the innate immune system which reacts rapidly to the pathogens. Whilst the adaptive immune system responds slowly to infection and also possesses a high degree of specificity. However, it is the activities of the innate immune system that prompt the

    The immune system is the most important system in the human body because it protects the body from strange objects, such as viruses, bacterium, and germs.

This overactive of the immune system can lead to many diseases, known as autoimmune diseases. These autoimmune include many diseases, such as

    is known as immune system(97). Immune system can be classified broadly in two sub-systems, the innate immune system versus the adaptive immune system, or humoral immunity versus cell mediated immunity.

Malfunctioning of immune system can result in autoimmune diseases, inflammatory diseases and cancer. Less active immune system results in
