Organs you can open while they work
A labelled diagram shows where the parts of an organ are. These simulators show what the parts do. The Heart Simulator pumps blood with valves that open and shut on time; the Respiratory System Simulator moves the diaphragm and the ribs and sends oxygen into the blood; the Kidney Simulator filters plasma and concentrates urine when ADH rises. The Endocrine System Simulator sends hormones from each gland to their targets and runs blood glucose, the thyroid feedback loop and fight or flight. Every organ can be cut open in 3D on a computer and studied as a clear 2D diagram on a phone.
Which simulator for which topic
| Topic | Open |

| Breathing, gas exchange, spirometry | Respiratory System Simulator |
| Digestion, enzymes, absorption | Digestive System Simulator |
| Excretion, osmoregulation, the nephron | Kidney Simulator |
| Hormones, blood glucose and feedback | Endocrine System Simulator |
| The nervous system and the lobes | Interactive 3D Brain Model |
| Vision and hearing | Human Eye Simulator, Human Ear Simulator |
| Bones, joints and support | Interactive 3D Skeleton |
A sensible order for a body-systems unit
Start with the skeleton and the organ systems it protects, then follow oxygen: breathing, then the heart that carries it. Digestion and the kidney come next, because both are about exchange and balance. Finish with the brain, the eye and the ear, where the body turns stimuli into signals. Each simulator has an Experiment mode with practicals from GCSE, IGCSE, AP Biology and the NGSS, and a Quiz mode for checking what stuck.
Educational models, not medical advice
The conditions you can switch on, such as a heart block, asthma or kidney disease, show the principle behind the textbook description. They are simplified teaching models and are not a guide to diagnosis or treatment.
