Respiration of the human being with Cobra SMARTsense

In this experiment, human respiration is illustrated by measurements of the oxygen and carbon dioxide content of ambient air and of repiratory air. Without the conversion of O2 into CO2, human life and the life of many other animals would not exist. Essential for this are also the plants, which convert CO2 into O2 through photosynthesis and thus provide us with a basic building block of our existence.
