Jeyrana can reduce the internal organs not to die from thirst

On the endless deserted expanses of Iran and Afghanistan, Jajaran lives - man-and-paint mammals from the genus Gazelle. The life of Jeyranov is full of dangers: besides wolves, tigers, leopards and berkuts they are threatened with a much stronger enemy - weather conditions. Sajrana not adapted to the long migration is often dying with a sudden weather cataclysm for these territories - for example, snow falling.

But much more often in the territories of Accommodation, the Jeyranans comes long droughts. As if giving up a debt for all the adversity and life, nature rewarded these man-fated amazing abilities to survive drought in those places where other competing mammals are unable.

First, Jeyran can do without any problems without water during the week. Secondly, these mannocardines adapted to drink even salt water (than the populations inhabiting the Caspian Sea coast). In addition, a large amount of moisture of Ceyranana can get a plant. But in case of the case of extreme needs, these animals have a secret ability to have no longer suspected of specialists for a long time.

The fact is that Jajanov has the lowest evaporation of moisture over the surface of the body in comparison with other workflows. In this regard, in addition to natural feces, the largest part of moisture from the body of the animal is excreted through breathing. It turns out that you can save moisture by lowing the respiratory frequency. And for this it is necessary that the internal organs consume less oxygen.

During the thirst for Jayranans, the volume of the most "oxygen-conspped" internal organs - heart and liver decreases by 40%. Thanks to this ability, the animal manages to reduce the loss of fluid during the strongest drought.

To learn about this amazing mechanism, scientists succeeded during the experiment on a group of 18 Jeyranans taken from wildlife and contained on a diet with a limited amount of liquid. After the end of the observations, the animals were given to get drunk and returned to the natural habitat.
