      Hi 322bera39,
      Breathing system or respiratory system consists of the organs that help to breathe. It includes:
      The nostrils: they bring air into the nose, where its warmed, humified and dust particles are removed
      Trachea or windpipe: windpipe. It filters the air we inhale and branches into the bronchi.
      Bronchi; two air tubes which carry atmospheric air directly into the lungs
      Lungs: Main organ where oxygen is taken into the body and carbon dioxide is expelled out.
      Diaphragm: Dome-shaped muscle located at the bottom of the lungs. Its movement allows space for lungs to expand or reduce.
      🙂
