    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

    IMMUNE SYSTEM All living organisms are continuously exposed to substances that are capable of causing them harm. Most organisms protect themselves against such substances in more than one way --- with physical barriers, for example, or with chemicals that repel or kill invaders.

Naturally acquired active immunity is where immune system has a chance to destroy the virus particles before they can enter a cell. The virus’ antigens alert the immune system to produce white blood cells to prevent the virus from spreading. White blood cells are the type of cells that are used to ward off any foreign pathogens in the body. The two white blood
