Innerverse uses reference anatomy for its whole-body entry map and reconstructed interiors for its seven rides. Vessel, heart, airway, stomach, intestinal, renal-tubule and axon shapes are teaching models, not scans of those interiors. The explorer, lighting, particle density, sizes and travel speeds are fictional or adapted for visibility.
The heart ride follows the right atrium, tricuspid valve, right ventricle, pulmonary valve and pulmonary artery, in that order. Its chambers are unfolded into a navigable route, not reproduced in their real spatial arrangement. The valves are held open for passage. Ventricular ridges and supporting cords are illustrative; this is not a simulation of valve mechanics, pumping or a complete four-chamber heart.
The lung ride follows a selected airway from the trachea through a bronchus and bronchiole to an enlarged, closed-ended alveolar airspace. Side branches are visible, but the vessel follows one route. Many branch generations and changes of scale are compressed. Tracheal cartilage supports are exposed through a simplified lining to show their shape. The final translucent wall lets you see a schematic capillary network outside the airspace. Blood cells remain in that network; the vessel does not cross the air–blood barrier. Gas exchange and breathing mechanics are not simulated.
OpenStax · Heart anatomy supports the distinction between ventricular ridges, supporting cords and the pulmonary valve.
This ride begins after the glomerular filter. It follows a representative proximal tubule, loop of Henle and distal tubule before entering a collecting duct. Collecting ducts receive fluid from multiple nephrons. They are shown as the next part of the drainage route, not as part of an individual nephron.
The route is enlarged and unfolded. The proximal brush border is exaggerated, and the loop's changes in epithelial thickness are simplified. No blood cells enter this passage. The small floating specks indicate fluid motion, not specific molecules. Filtration, transport across the lining and urine concentration are not simulated.
The brain entry begins inside a representative axon. This is a cellular interior, not a tunnel through the brain. Microtubule bundles surround a fictional open flight corridor. Vesicles and mitochondria represent transported cargo; their movement is not an electrical nerve impulse. Myelin is outside the axon membrane. Motor proteins, organelles, spacing and time are enlarged or simplified for visibility.
The outer surface of the mitochondria is transparent to reveal a schematic folded interior. Natural mitochondria do not look like these lit cutaways. The ride does not model a complete neuron, synapse or action potential.
The gut lumen is the space that carries food and digestive contents. It does not connect directly to the interior of a blood vessel. Switching between routes starts a separate journey. In particular, switching from the heart to the lung airway changes from a blood-filled space to an air-filled space; these are not directly connected. The stomach-to-intestine transition follows the order of the digestive tract but omits the intervening detail of the duodenum before entering a representative jejunal segment.
Stomach pits, intestinal villi and blood cells are enlarged to be visible. Intestinal microvilli are not individually modelled; enlarged microvilli are shown in the separate kidney-tubule ride. The gut contents are represented by particles; they are not literal nutrient molecules. The stomach lining is shown folded rather than modelling its changing distension. No blood-flow, peristalsis, absorption or patient-specific physiology is simulated. These models have not undergone independent clinical validation.

Geometry supplied through human-atlas: converted axes and units, simplified geometry, quantized normals and binary packing. Innerverse selects and combines structures, rescales them and adds its own materials and animation. The interior rides are schematic additions. Stomach, duodenum, jejunum, ileum and both kidney surfaces have been included in the reference entry map. The reference is based on adult male anatomy; it does not represent every anatomical variation.

Five lobes retained, geometry repacked, centred, scaled and recoloured. The HRA and BodyParts3D reference models come from different source datasets; their arrangement is an educational composite.
The entry-map lungs have three right lobes and two left lobes.
