if a patient is infused with an isotonic saline solution, where will the fluid end up? Extracellular environment? Intracellular environment? Both? Can you please explain your answer? Thank you so much!
The fluid will be in both environments at the end of the procedure. The cell immersed in an isotonic solution is in an equilibrium state - the fluid molecules diffuse through the cell membrane in an equal amount inside and out, without accumulating and not losing a cell.
