Now, recall that water always naturally moves from a lower solute concentration to a higher solute concentration. Water always moves from a high osmotic potential to a low asthmatic potential. And because a greater solid concentration means a lower osmotic potential, water will always move from the tissue side to the blood plasma side of our capillary. So, in the same exact way that objects always travel from a higher gravitational potential to a lower gravitational potential, water will always move from a higher osmotic potential in the tissue to a lower osmotic potential inside our blood vessel. And that's why water moves along this direction into our capillaries. So, due to the high level of proteins, ions and other solute molecules in the blood, the blood plasma has a greater solute concentration than the tissue of the membrane, and that means it has a lower osmotic potential.
