A patient with kidney failure undergoes dialysis treatment to clean their blood.

A detailed diagram showing a section of a dialysis machine's filtration tube. Inside the tube, blood flows in one direction, containing a high concentration of urea molecules (represented by small circular dots). Outside the tube, dialysis fluid flows in the opposite direction (counter-current), containing no urea. The boundary between the blood and the dialysis fluid is labeled as a partially permeable membrane with tiny pores through which the small urea molecules are shown passing from the blood into the dialysis fluid.

Describe how urea is removed from the patient's blood as it passes through the dialysis machine.
