Nursigo · Anatomy essentials
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.
Respiratory · Visual study
Understand the lungs
Locate the lobes and connect the conducting airways to gas exchange.

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. Trachea
- 2. Bronchi
- 3. Bronchioles
