They are experts at storing water and they can hydrate quickly

Although camels don't have water reservoirs in their humps, they are excellent water savers. Heterothermy is how camels control their body temperature all day long. They can conserve water by not sweating amid daily temperature rises. Additionally, to preserve water, the camel exhales, trapping water vapor in its nostrils, which is then reabsorbed into the body. In cooler climates, camels may consume enough moisture from their green plant food to keep their bodies hydrated without drinking.

Besides, a camel's kidneys and intestines are excellent at reabsorbing water. In the kidneys of the camel, the ratio of the cortex to the medulla is 1:4. As a result, the medullary portion of a camel's kidney is twice as large as that of a cow. Second, the surface area for filtration is reduced by the lower diameter of renal corpuscles. In the harsh desert environment, camels can preserve water and produce less pee because of their two main structural features.

Thus, Camels can survive for extended periods without access to external sources of water because of several physiological adaptations. Even in extremely hot weather, the dromedary camel may go up to ten days without drinking, and it can lose up to 30% of its body mass as a result of dehydration. However, once they find a water source, a 600 kg (1,300 lb) camel can drink 200 L. This is the equivalent of 53 US gallons and all of that in just three minutes. This happens because the red blood cells of camels are oval as opposed to circular in other animals. This improves the flow of red blood cells during dehydration and makes them better at withstanding significant osmotic fluctuation without rupturing while drinking huge volumes of water.
