See the anatomy.
Make the connection.

Turn structures into understanding with focused organ exploration, short study notes and free knowledge checks. Start with an illustration, then open 3D when you want a closer look.

Understand the lungs

Locate the lobes and connect the conducting airways to gas exchange.

Anatomy illustration
Anterior illustration of both lungs and trachea: three lobes on the patient's right and two on the left.

Optional 3D download: 5.9 MB. Study notes and questions work with the illustration too.

Right and left always refer to the person, not the viewer.

Choose a structure

Read its role below. Open 3D to isolate it in the model.

Start with the whole organ

Locate the lobes and connect the conducting airways to gas exchange.

Follow air toward the exchange surface

  1. 1. Trachea
  2. 2. Bronchi
  3. 3. Bronchioles
  4. 4. Alveoli

Exam connection

Distinguish ventilation (moving air) from gas exchange (diffusion between alveoli and blood). Use the patient's right and left when describing anatomy.
