Trace the connections between a meal, circulation, breathing, movement and hearing.
Interactive explorationBuild a virtual light filter, uncover a missing patch, explore real skin microscopy and inspect a DNA structure. Discover why visible light and warmth cannot tell the whole story.
Interactive explorationOpen a connected follicle, follow its normal oil route, and compare structures hidden beneath the surface. Read real human microscopy and discover why acne is more than a story about dirt.
Interactive explorationFollow a meal through the gut, then zoom into its lining. Choose starch, protein or long-chain fat and discover why their next routes differ.
Interactive explorationTurn a real anatomical model in your hands. Reveal its chambers, meet the four valves, then follow the blood moving through both sides of the heart.
Interactive explorationInspect real urinary anatomy, follow a glucose marker out of blood and back again, and discover three different crossings with a ledger that never loses a marker.
Interactive explorationMove through a breath, connect space to airflow, then cross the tiny boundary where oxygen enters the blood.
Move a load closer to an elbow on a transparent teaching arm. See the force change, then explore how muscles can work without visible movement.
Interactive explorationNudge a membrane, discover when a spike appears, test its recovery, and cross a chemical synapse. Then inspect a real potassium-channel structure.
Interactive explorationStart with a vibration. Follow air, eardrum, tiny bones and hair cells, then see why the message reaching your brain is a different kind of signal.
