Final answer:
In-center hemodialysis uses sterile dialysate which is a solution of sterile water, glucose, amino acids, and electrolytes. The dialysate has a higher solute concentration than the blood in the upper component, allowing the urea to diffuse to the lower dialysate through the semipermeable membrane, effectively removing waste from the blood.
Step-by-step explanation:
In-center hemodialysis uses sterile dialysate.
The dialysate used in hemodialysis is a solution of sterile water, glucose, amino acids, and electrolytes. It is designed to remove waste molecules like urea from the blood through the semipermeable membrane of the dialyzer.
The dialysate has a higher solute concentration than the blood in the upper component, which allows the urea to diffuse to the lower dialysate through the membrane, effectively removing waste from the blood.
