National Geographic Channel (NGC) takes you deep into the human skin, showing the wonderful changes of our body from the first cry to the death in old age, as well as the wonderful biological system we rely on for survival. The production team of "Journey Inside the Body" is the same as that of "Diary of the Uterus". They used a milestone technology that has not been used in television so far to explore the growth stories happening in the human body every day. The production team adopted microscopic photography technology, advanced medical technology and cardiac CT imaging technology to show how the human body works, grows and matures from childhood, youth, adulthood to old age.
