Explore the human lymphatic system (lymph nodes, spleen & thymus) 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 lymph nodes and lymphoid organs of the human body, then score as high as you can in the 12-question Node Quest quiz. Get 9 or more right to earn the Immune Expert badge.
Lymph nodes are green, the spleen is purple, the thymus is amber and the tonsils are pink, inside a faint see-through skin.
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 lymph node or organ to see its name and region. Use the region buttons to show or hide the head and neck, arms and armpits, chest, abdomen, pelvis, or legs and groin. Press Start Node Quest Quiz to answer 12 questions: tap the named lymph node or organ 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 Immune Expert badge. Your best score is saved on this device.
