Final answer:
Small waste molecules such as potassium, creatinine, and urea occur at a higher concentration in the blood and at a lower concentration in the dialysate. Diffusion moves these waste molecules from the blood to the dialysate.
Step-by-step explanation:
Small waste molecules such as potassium, creatinine, and urea occur at a higher concentration in the blood and at a lower concentration in the dialysate.
Diffusion moves these waste molecules from the blood to the dialysate.
Therefore, the correct choices are: small waste molecules occur at a Higher concentration in the blood and at a Lower concentration in the dialysate.
Diffusion moves these waste molecules From the blood To the dialysate.
