Episode 11: Our body / The brain

The wonder of our body. How is the human body structured? What gives it support, and how can we move? How does the eye work? How do we hear? Join us on an exciting exploration into the wondrous world of bones, muscles, and sensory organs. The body is controlled by the most complex organ that nature has ever produced: the brain. Our thinking organ is always at work, even when we sleep. Without our conscious effort, the heart and breathing are regulated. The brain folds consist of billions of nerve cells. With their help, we perceive the world, learn, remember, make plans, and dream during sleep.
