Inside the Living Body (2007x7)

Date de diffusion: Sept 16, 2007

From our first cry to our last breath, our bodies undergo a continuous second-by-second transformation. Every move we make and every outside stimulus triggers a reaction through the skin, bones, organs, muscles and cells. We breathe, on average, 700 million breaths in a lifetime; an adult skeleton is replaced every seven to 10 years; we shed as many as 30,000 dead skin cells every minute; and the food we eat travels 30 feet (9 meters) on its journey through our bodies. This documentary takes you beneath the skin to reveal how our bodies evolve from birth to old age, and the amazing biological systems we need to thrive.
