The respiratory system consists of a network of tissues and organs which perform the process of breathing.

How does the respiratory system work?

  • The respiratory system allows us to breathe. It performs the function in 2 steps consisting of inhalation (breathing in oxygen) and exhalation (breathing out carbon dioxide).
  • The respiratory system is made up of various organs which allow this exchange of gases.
  • In a series these organs include nose, mouth, pharynx, larynx, trachea or windpipe, bronchi (large airways), bronchioles (small airways) and lungs.
  • These organs together form the upper and the lower respiratory tract.
  • The lungs are a pair of cone-shaped organs that take in oxygen.
  • During respiration, air enters your body through your nose or mouth.
  • Then the air travels through the larynx and trachea.
  • From here, the air moves into the lungs by passing through main bronchi.
  • One main bronchus leads to the right lung and one to the left lung:
  • Here, the bronchi divide into smaller tubes called bronchioles.
  • Bronchioles end in tiny air sacs called alveoli where the exchange of oxygen and carbon dioxide occurs.
  • Carbon dioxide is then exhaled out.
