Final answer:
When urine concentration is not present, it disrupts osmotic balance in the body. Normally, the kidney reabsorbs solutes and water to create urine, and adjustments are made to concentrate solutes. In dialysis machines, the concentration of solutes differs between the blood and dialysate to remove wastes.
Step-by-step explanation:
When the concentration of urine is not present due to membrane recycling, there will be a shift in concentrations which disrupts osmotic balance. This means that the osmotic pressure, or the concentration of solutes, in urine will be different from what is normally expected.
Normally, the kidney reabsorbs about 82 percent of solutes and water, and as the forming urine enters the ascending loop in the kidney, adjustments are made to the concentration of solutes to create what is perceived as urine.
In the context of dialysis machines used by patients with kidney illnesses, the concentration of solutes is likely to differ between the upper component of the dialyzer and the lower compartment of the fresh dialysate. This difference helps in the successful removal of wastes from the blood through diffusion across a semipermeable membrane.
