Consider a patient undergoing kidney dialysis, whose blood has bicarbonate at a concentration of 14 mmol/L and urea at 23 mmol/L. The dialysing liquid has bicarbonate at 32 mmol/L and urea at 0 mmol/L. In which direction will these substances flow?
- bicarbonate will flow from patient’s blood to dialysing liquid, urea will flow from patient’s blood into dialysing liquid.
- bicarbonate will flow from dialysing liquid to patient’s blood, urea will flow from dialysing liquid into patient’s blood.
- bicarbonate will flow from dialysing liquid to patient’s blood, urea will flow from patient’s blood into dialysing liquid.
- bicarbonate will flow from patient’s blood to dialysing liquid, urea will flow from dialysing liquid to patient’s blood.
C: molecules will flow from areas of high concentration towards areas of low concentration. Hence bicarbonate will flow from the dialysing liquid at 32 to blood at 14 mmol/L, while urea will flow from blood at 23 mmol/L to the dialysing liquid at 0 mmol/L.
