The immune system is a system of many biological structures and processes within an organism that protects against disease.To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.isorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections.
A truffle is the fruiting body of a subterranean Ascomycete fungus, predominantly one of the many species of the genus Tuber.
