The immune system is the body’s first line of defense against harmful invaders, such as viruses, bacteria, and other foreign bodies. The immune system consists of various organs, cells, and tissues, such as the skin, lymph nodes, tonsils, thymus, spleen, bone marrow, white blood cells, and microbiota.

Its pivotal role is to distinguish our tissue from foreign cells and to initiate an immune response when exposed to dangerous pathogens and subsequently defend against infection.
