The human body is always on the move. Whether we are jumping, running or sitting still; blood is pumping, muscles are contracting, and joints are moving. The body's internal systems perform complex processes every second of every day, so we can spend our time doing whatever we need to. This Australian-made, curriculum-fit programme takes us inside the human body, showing us just how the musculoskeletal and cardio-respiratory systems work and how they influence and respond to movement.
