The fifteen amazing pictures of the human body below were all taken using a scanning electron microscope (SEM) and allow you to see much closer detail of what is inside your body. We will start with the head, travel through the thoracic cavity and arrive at the abdominal cavity for this journey of self-discovery and allow you to experience first hand the incredible power of the scanning electron microscope. During this journey you will also get to see what happens when cells are ravaged by cancer and the incredible moment when an egg is approached by sperm for the very first time.
