In this companion website to the NOVA program, Electric Heart, there are a variety of interactives to help students better understand the human heart.  Scan over a cross-section of heart to see how it works.  Learn amazing heart facts.  Discover advances made in artificial parts to replace damaged and missing ones.  Learn about a pioneering artificial heart  and transplant surgeon, O. H. Frazier.  Perform a simulated heart transplant.

From site:  GetBodySmart represents my attempt to create a fully animated and interactive eBook about human anatomy and physiology. The contents and design of this long-term project are based on my 21 years of teaching this material at the university level.

While it is being constructed, I invite all interested teachers, students, healthcare professions, and others to use the free tutorials and quizzes in GetBodySmart to help explain the body’s complex physiological interactions and illustrate its important anatomical landmarks.

The site is in the very early stages of development, and a lot of content is still missing. Please be patient. Even though my pace is somewhat slow, I try to make additions/updates every day. Because this is a large and complicated project, it will realistically take me many years to develop GetBodySmart into a truly comprehensive learning resource.

From site:  Explore resources for students and teachers interested in learning about the cardiovascular and circulatory systems. Movies of the heart in action, online and at-home activities, links to other sites about the heart and lungs, and much more!

From site:  Click on a body part to watch movies, take quizzes, read articles, solve word finds, and do activities — all about the parts of your body!

Human Anatomy Online provides free interactive animations, graphics and descriptions for the human body for students and adults.
