Question

1. What are the key parts of the breathing process?

Answer 1

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.
