Explore the human respiratory system (lungs, trachea & bronchi) in 3D in your browser. This free educational game is built with Three.js and WebGL by Indie Forge Studio and works on phones, tablets and desktop with no download.
Learn the lung lobes and airways of the human body, then score as high as you can in the 12-question Breath Quest quiz. Get 9 or more right to earn the Lung Expert badge.
The lung lobes are see-through pink so you can see the branching bronchial tree inside, with a see-through skeleton around them.
Every correct answer scores 100 points plus 20 for each answer in your streak. A miss or skip resets the streak. You finish with a rank from First-Day Intern up and up to three stars.
Press Tap to Play, then drag to rotate the model, pinch or scroll to zoom and tap any airway or lung part to see its name and region. Use the region buttons to show or hide the upper airway, the trachea and bronchi, or the lungs. Press Start Breath Quest Quiz to answer 12 questions: tap the named airway or lung part on the model, name the highlighted one, or answer an anatomy fact.
Each correct answer is worth 100 points plus 20 points for every answer in your current streak. A wrong answer or a skip resets the streak. At the end you get a rank and up to three stars, and 9 or more correct answers out of 12 earns the Lung Expert badge. Your best score is saved on this device.
Yes. The game is free and runs instantly in your web browser on phones, tablets and desktop computers. There is nothing to download or install.
