NettetThe first step is the passive or active movement of water and dissolved substances from the fluid inside the tubule through the tubule wall into the space outside. The second step is for water and these substances to move through the capillary walls back into … NettetThe movement of water across cell membranes can affect cell volume, shape and cell survival. Isotonic solutions = 290-300 mosm = 0.9% saline = no net diffusion of water ; Hypertonic solutions = > 300 mosm = net diffusion of water into solution, out of cells ; Hypotonic solutions = < 300 mosm = net diffusion of water out of solution, into cells
