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. Truffles are ectomycorrhizal fungi and are therefore usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi.
Chocolate truffles are a dessert delicacy that began in Europe. They are mainly made of ganache (a chocolate based cream) and some type of coating. This coating can be in the form of cocoa powder, solid chocolate that is dark, milk or white, or some sort of confection. They are rolled into imperfect ball shapes and are often given as gifts for special occasions. The best gourmet chocolate truffles are the ones with a savory assortment of fillings. Classic chocolate truffle fillings include chocolate ganache, liqueur, different flavors of cream, nougats, and caramel. Modern fillings may be fruit, fudge, marshmallow, or chocolate chips.
