A camel can survive several weeks without drinking water by simply eating green plants. When a camel does drink, however, it can store up to 200 liters of liquid. This feat is possible because a substance in its blood allows its body to absorb moisture much faster than a human body.
This is because since the can store the water it would be water regulation. ( I just did a assignmet with this exact question and I got it correct) hope that helps :)
