Human Brain
Every organism, no matter whether it is an earthworm, a snail, a fish or a human being, takes in information from the environment through differently structured sensory organs. This was absorbed first by a diffusely organised nervous system, which, in the course of evolution, has been replaced by a hierarchically organised one. Eventually a controlling centre has developed that interconnects and coordinates the nerve impulses supplied by receptors, reacts appropriately and is called the brain. In more highly developed organisms a part of the body has developed into a head, in parallel to the development of the brain.

Human Dignity
This is Albertine. She is seven years old. Three years ago, she lost her mother and has lived with her grandmother ever since, her father has left them. Every noon she comes to have lunch in the ward. The girl seems to feel her strength ebbing away and has decided not to talk anymore. The children at this stage believe that the grown-ups can prevent death but see that they're not doing so. Thus, they seal themselves off and retreat into their own world. And when this happens, Sister Marie Stella and her team prepare the children for death, just as they do with the grown-ups. Albertine was allowed to chose a dress from the dressmakers for the Christmas celebration.

Human Liver
Normally you do not feel it, it does not beat like the heart, neither can we feel it like the lungs when we breathe in and out – nevertheless, it is one of our most important organs: the liver.

Hunters and Hunted
The African night is not for sleeping. A lot is going on there. The hunters are lying in ambush and the preys are on alert. Predators are mammals. Scientifically they are called carnivores. But other predatory vertebrates such as cats, jackals, hyenas and crocodiles are colloquially termed »predators«. They feed on meat but are not very selective in doing so. As they are not specialised in one type of animal but eat all vertebrates as well as carrion, they are called opportunistic feeders, which means they target the food that is easiest for them to catch, in the shortest time and with minimum energy input.

Hybrid Drives
When Lena goes through the city centre by car, she has to be particularly careful, because her car is almost inaudible and therefore pedestrians often hear it just in the nick of time. For in the city centre, her car is powered by electricity. The power is provided by a strong battery in the boot.

Hydrological Cycle
Water is the source of life because life on our Earth originated in, more precisely, under the water. Water is essential for animals, plants and for us humans. Without water survival is impossible. Pure water is transparent, it smells and tastes of nothing. But where does the water come from? Where does it flow? And what happens to the water we do not use?
