                  What is the respiratory system?


                  It is a group of organs that allow the person to breathe. Its main


                  function is to supply oxygen to all the internal body parts, by



                  inhaling oxygen and exhaling carbon dioxide.



                  The respiratory system is made up of the nose, pharynx, larynx,


                  trachea, bronchi and lungs.
