From the moment we are born, each one of us goes through a series of extraordinary transformations as our bodies change. But have you ever thought about what our bodies really do every second, every moment, to keep us alive? How the body copes as we develop from a fertilised embryo to a newborn; how we change so fast in the first few years of our lives; how eating, drinking, playing sports and having sex change our physiology; and how different we are as men and women? Body in Numbers will demonstrate, using a mix of visual events, graphics and live action, what makes us the way we are in a unique and compelling way. It will show the consequences of our everyday actions as our bodies react and adapt. Based on amazing facts and calculations, the series explores the body's facts in numbers. We'll decode the body's vital statistics showing how the heart pumps about 1 million barrels of blood during an average lifetime, how the surface area of a human lung is equal to that of a tennis court, how the femur is the strongest bone in your body and is as tough as concrete and much more.
