What is tonicity? - Answer-The ability of a solution to cause a cell to shrink or swell. Why does it matter if you are hypotonic or hypertonic? What happens during these conditions? - Answer-If the interstitial fluid has greater solute concentration than that of the cytosol, water from inside the cell flows out causing the cell to crenate and blood pressure to increase. If the interstitial fluid has less solute concentration than that of the cytosol, water flows into the cell and it undergoe...
