Osmosis is defined as the spontaneous flow of water into a solution, or, from a more dilute to a more concentrated solution when the two solutions are separated from each other by a semi-permeable membrane. The liquid inside them comes out and try to dilute the salt concentration and maintain the mucus layer, and hence, they end up shedding water. The flow of water will be prevented when both the pressure (inside and outside) are equal. Mintorovitch J, Yang GY, Shimizu H, Kucharczyk J, Chan PH, Weinstein PR. AJR Am J Roentgenol.
