Nursing With Ima • Respiratory TEAS 7 Lesson

Follow the Flow of Air

Follow air through the respiratory pathway and learn what each major structure does.

Before you begin: Air travels through the respiratory system in a specific sequence. Your goal is to learn that sequence and understand the role of each major structure along the way.

Follow the Flow of Air

Click through each structure to follow the pathway from the nasal cavity to the alveoli.

Step 1

Nasal Cavity

Entry point for air. It warms and moistens incoming air.
Think: air enters here

✓ Pathway Complete!

You followed air from the nasal cavity all the way to the alveoli.

TEAS Tip
When a question asks, “Where does air go next?” Follow the respiratory pathway in order.

Bronchi → Bronchioles → Alveoli
Think of the airways becoming smaller as air moves toward the alveoli.

Now You Try It

Build the respiratory pathway in the correct order. Start with the structure where air enters the respiratory system.

✓ You built the pathway correctly!
Nasal cavity → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli

Quick Memory Connections

  • Bronchi = larger airways
  • Bronchioles = smaller branches of the airway
  • Alveoli = where gas exchange occurs
