Keywords: tick physiology, tick salivary glands have been shown to be important in both water elimination and ionic regulation, electron microscopic studies of the salivary glands of several species of hard ticks and one species of soft ticks show the presence of cells with ultra-structural features common to transport epithelia, it is concluded that the transport epithelia of the granular alveoli in hard and soft

ticks function to product the water portion of the saliva, and in hart ticks also function in water elimination and ion regulation especially in the latter part of feeding
