Structure, Function, Training
When we talk about muscles, we mostly think of those we can see. These are the arm, chest, abdominal and leg muscles. The muscles have to fulfil various tasks in the human body. On the one hand, they serve the movement and upright posture of our body, on the other hand, the contraction of hollow inner organs such as the intestine, bladder and blood vessels. The third task is maintaining blood circulation.

Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
