The camel can live 7 days without water, but not because he keeps a week water supply at himself in humps. They can avoid dehydration which would kill the majority of other animals thanks to a large number of oval red blood cells (unlike usual rounded shape). Blood keeps normal fluidity even at strong condensation as narrow oval erythrocytes freely pass through capillaries. Besides, erythrocytes of a camel have ability to accumulate liquid, increasing at the same time in volume up to 2,5 times. Hump it that other as big heap of fat. The fat which is contained in humps isn't split on water as was considered throughout long time, and plays a food stock role for an organism. He also serves for thermal insulation of a body of a camel, collecting first of all on a back which is most subject to influence of sunshine.
