The Virtual Body 
I was shown this site by a nursing student at my school, and I thought it was really neat, so I wanted to share it with all of you.
When the site loads, select the language you want to view it in: English or Spanish. And then you’ll be whisked away to the menu page.
On the menu page, you’ll find four Virtual Body Maps: The Human Brain, Skeleton, Human Heart, and Digestive Tract. To navigate, just select which map you want to view.
Each section has some sort of narrated tour or guide and a way for you to test your knowledge. You’ll also find that each section has its own extra information: for example, the Human Heart section has an animated heart.
