So, for example, suppose we apply some pressure to our cell membrane, and if this pressure equals asthmatic pressure, well, then no osmosis will occur, no movement of water will occur. And this becomes very important when you're talking about hydrostatic pressure and asthmatic pressure in the capillaries of our body. So the last thing I want to talk about is a formula. And this formula could be only used when we talk about ideal conditions. So ideal solutions and solutions that have very low or small concentrations. Now, if you want to look at a problem using this formula, check out the link below.
