Anatomical models for scientific, instructional, and educational purposes, namely, medical demonstration devices used to simulate blood circulation in the human body

Replication of the heart and lungs of the chest cavity for educational purposes, namely, a training tool that demonstrates blood flow to the heart during cardiopulmonary resuscitation consisting of a small plastic plate backed with an instruction card and with a plastic dome covering the plate encasing the heart and lungs of the chest cavity, whereby pressing on the plastic dome simulates chest compressions, the heart and lungs expanding and contracting to demonstrate blood flow
