Innerbody.com offers good diagrams of the skeletal, muscular, cardiovascular, digestive, encodrine and nervous systems, as well as respiratory, immune or lymphatic, urinary, female reproductive, male reproductive and integumentary systems. Users can navigate and further explore the different systems through tabs on the left side of the page.
After clicking on specific system's tab, users can view both a 2-D interactive view or a 3-D rotate and zoom view. On the left side of the page is an anatomy explorer with links that users can click on to zoom into specific zones of the body to see every single body part, including those that are too small to see from the regular view. On the right side of the page are larger images of the body part belonging to that particular system and information about its function.
