The video shows a 3D model of a human head and upper body. The model is semi-transparent, allowing the viewer to see the internal structures. The brain is prominently displayed in the center of the head, with the cerebellum and brainstem visible behind it. The model also shows the sinuses, nasal cavity, and throat. The heart and major blood vessels are visible in the chest area, with the aorta and pulmonary artery clearly shown. The model rotates slowly, providing a 360-degree view of the internal structures.
