Human Lung
Structure and Function
Only rarely do we notice that we need them: our lungs. Mostly, we breathe unconsciously and shallowly – especially if we have a sitting job. Only when we exert ourselves, for example when we run particularly far and fast, do we realise that our breathing quickens and becomes more laborious – or that we get out of breath sometimes. This adaptive capacity of our lungs, their flexibility in responding quickly and effectively to various physical requirements is one of the many amazing abilities of our body which keep it viable. Only when we inhale the oxygen supplied to our body via the lungs as the basis for combustion, are we able to generate the energy our body’s cells need to survive.

Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
