The+immune+system

The immune system is the system is a system that helps shield you from bacteria, mould, colds and diseases. The skin is the first layer of the immune system. The skin helps shield your organs and lymph system and blood vessels from bacteria, mould, colds and diseases. The skin also has many lymph nodes. Lymph nodes belong to the lymph system, a network of different vessels which transport white blood cells, or phagocytes  (  fag   -   //uh//   -sahyts   )  , trough the body to fight diseases. Phagocytes  (  fag   -   //uh//   -sahyts   )   are a cell in the body's bloodstream and tissues, e.g. a white blood cell that eats and destroys diseases and bacteria. Mucous ( myoo   -k   //u//   h  s) (also know as snot) sheets are cells that line all openings of the body. When dust enters the body it gets caught in the mucous sheets and become digested by the mucus. You have nose hairs that filter out dust so it does not enter the body and when you sneeze it is the body’s way of getting rid of dust from your lungs. The lymph system is made up of T and B cells, antibodies and platelets that rush to the wound and help stop blood coming out by making scabs.
