Er versorgt jede Zelle mit Energie und gibt Lebewesen die Kraft, sich zu bewegen, zu wachsen und zu \u00fcberleben. Menschen nehmen Sauerstoff \u00fcber ihre Lungen auf, indem sie ihn mit jedem Atemzug aus der Luft aufnehmen. Die Lungen geben ihn an das Blut ab, das ihn in alle Teile des K\u00f6rpers transportiert. Im Gegenzug wird Kohlendioxid als Abfallprodukt abgegeben. <em>F\u00fcr Lebewesen unter dem Meer funktionieren die Dinge anders.<\/em>Es gibt keine Luft zum Atmen, nur Wasser. \u00dcber Millionen von Jahren haben Meereslebewesen erstaunliche Wege entwickelt, den darin enthaltenen Sauerstoff aufzunehmen.<\/p>\n<h3><strong>Wie atmen Fische unter Wasser?<\/strong><\/h3>\n<p>Fische besitzen keine Lungen wie wir. Stattdessen atmen sie durch spezielle Organe, die Kiemen genannt werden. Diese Kiemen \u00fcbernehmen die lebenswichtige Aufgabe des Gasaustauschs \u2013 sie nehmen Sauerstoff auf und geben Kohlendioxid ab. Jede Kieme besteht aus <!--more-->aus d\u00fcnnen, zarten F\u00e4den, die mit winzigen Blutgef\u00e4\u00dfen gef\u00fcllt sind. Das verleiht ihnen ihre leuchtend rote Farbe.
