BioDigital Human is a website that offers a dramatic virtual 3D simulation of the human body. It can be used to explore human anatomy as well as teaching about various health conditions. It's a great tool for learners ranging from middle school kids fascinated with the human body to medical students (there's also a professional version for actual doctors to use).
This amazing body visualization
platform offers unprecedented access to the human body, for free. The
ability to annotate, personalize, and save items will move anatomy
studies beyond simple memorization into another class: a clearer
understanding of the human body.
