Featuring the same highly realistic visual elements as YOU!’s Giant Heart, the Virtual Heart app invites users to explore multiple views of the human heart: an external view and three internal views that realistically depict the heart’s valves, blood flow and electrical system. Offering an internal journey into the human heart most people may not have ever experienced, users can choose to turn on labels that identify different areas of the heart’s structure and can slide their finger up and down the screen to change the view of the heart from external to internal. Red and blue color streams visualize blood flow, and flashes of light highlight the heart’s electrical system.
