Question

What was the historical use of cellophane tubes in hemodialysis?

• A. Providing structural support to dialysis machines
• B. Acting as semipermeable membranes
• C. Delivering medication to patients
• D. Filtering blood cells directly

Hint:

Semipermeable membranes are crucial in hemodialysis as they allow the selective removal of waste products and excess fluids from the blood while retaining necessary blood components.

Answer 1

The Correct Option is B

Correct Option: 2

Role of cellophane tubes in dialysis:
Providing structural support to dialysis machines: Cellophane tubes do not serve a structural function in dialysis machines.
Functioning as semipermeable membranes: Historically, cellophane was employed in hemodialysis machines due to its semipermeable nature. This allowed for the selective removal of waste products and excess salts from the blood, while keeping blood cells and vital proteins intact.
Administering medication to patients: Cellophane tubes are not utilized for medication delivery.
Directly filtering blood cells: Although cellophane membranes facilitate filtration, their principal function was to act as semipermeable barriers, not for the direct filtering of blood cells.
Conclusion: The historical application of cellophane tubes in hemodialysis was predominantly based on their semipermeable characteristics, which facilitated efficient dialysis by removing waste materials from the blood.
