The proteins of the blood plasma being hydrophilic colloids in solution must exert an osmotic pressure. This osmotic pressure measures the momentum of the impacts made by the colloid particles on a unit of surface. Water and salt will pass from the outside to the inside of a tube whose wall is permeable to salt and water but is not permeable to colloid particles if there is a salt solution within the tube containing a hydrophilic colloid dispersed in it. Water and salt entering the tube increase the hydrostatic pressure of the fluid within it until this hydrostatic pressure exactly
