A yellowish, semi-transparent substance is floating and moving forward in the middle of the scene. There are small specks of light scattered throughout. The environment has a warm, labyrinthine quality, and the internal color of the tissue is a light red. The entire scene conveys a sense of healthy, balanced internal organ function. The depth of field is shallow, with the focus on the yellow substance. 3D animated rendering.
