what is human respiratory system? air passage way and disease revealed to air passage way

  RESPIRATION respiration is a physical process of gaseous exchange between the organism and its environment also known as breathing or ventilation inhaled air have more amount of oxygen and less amount of carbon dioxide whereas the exhaled air have more amount of carbon dioxide and very less amount of oxygen                   important point here is that respiration is not to be confused with cellular respiration because of following reasons  as simple respiration is defined as exchange of respiratory gaseous between the organism and its environment where as cellular respiration is defined as a process by which cells of a living organism utilizes oxygen and produces carbon dioxide extracts energy from this process and conserve this energy for later use and store it in biological useful forms such as ATP the second main difference between respiration and cellular respiration is that respiration is a physical  process whereas cellular respiration is a chemical and biochemical
