FOCUS QUESTION

How does the respiratory system move air and exchange oxygen?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Respiratory System air enters through Nose.
  • Nose down the Trachea.
  • Trachea branch into Bronchi.
  • Bronchi lead to Lungs.
  • Lungs end in Alveoli.
  • Alveoli exchange Oxygen.
  • Respiratory System powered by Diaphragm.

How to read this map

Follow air from the nose down the trachea and bronchi to the lungs and alveoli, where oxygen is exchanged.

Learning objectives

  • Order the respiratory passages.
  • Explain gas exchange in the alveoli.
  • Describe the diaphragm’s role.
  • Relate structure to breathing.
