The video shows a person's hands holding a plastic model of a human body and placing different organs into the chest cavity. The model is made of a translucent material, allowing the viewer to see the internal organs. The person places a red organ, which appears to be the heart, into the chest cavity, followed by a brown organ, which could be the liver. The person then places a black organ, which could be the stomach, into the model. The video provides a clear view of the organs and their placement within the body.
