Aquaporins would be expected to increase in numbers when there is an insufficient amount of water present in the blood.
Aquaporins are a type of proteins which are present in the integral membrane of the cells. They act as channels and help in the transport of water and small solutes across the membrane.
Whenever there is insufficient amount of water present in the blood, the antidiuretic hormone or the ADH responds. The aquaporins increase in number in the blood. They allow the transcellular reabsorption of water. Due to this fact, more water is able to escape from the collecting tubules and enter the blood.
