According to the passage, solute transfer in dialysis is faster ----.
In dialysis with an artificial kidney, the rate of
movement of solute across the dialyzing membrane
depends on four variables: the concentration gradient
of the solute between the blood and the dialyzing
fluid, the permeability of the membrane to the solute,
the surface area of the membrane, and the length of
time that the blood and fluid remain in contact with
the membrane. Thus, the maximum rate of solute
transfer occurs initially when the concentration
gradient is greatest (when dialysis is begun) and
slows down as the concentration gradient is
dissipated. In a flowing system such as
haemodialysis, in which blood and dialysate fluid flow
through an artificial kidney, the dissipation of the
concentration gradient can be reduced, and diffusion
of solute across the membrane can be optimized by
increasing the flow rate of either or both the blood
and dialyzing fluid.
