This interactive atlas illustrates the internal structure of a human body.
For user benefit, all internal organs are divided into skeletal, muscular, respiratory, circulatory, immune, digestive, endocrine, urinary, nervous, and reproductive systems. You can view the desired system by selecting an appropriate switch button. If you choose several switch buttons, several systems of the organism will be shown with respect to their placement alongside each other. Press "Clear All " button to deselect all systems at once.
Place a cursor over any organ on to see its name.
