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

Examine the role of cellophane tubes : 
Providing structural support to dialysis machines: Cellophane tubes are not used for structural purposes. 
Acting as semipermeable membranes: Historically, cellophane was utilized in hemodialysis machines for its semipermeable properties, allowing selective passage of substances like toxins and excess salts from the blood while retaining blood cells and essential proteins.
Delivering medication to patients: Cellophane tubes are not used for medication delivery. 
Filtering blood cells directly: While cellophane membranes allow for filtration, their primary role was to act as semipermeable barriers rather than directly filtering blood cells. 
Conclusion: The historical use of cellophane tubes in hemodialysis was primarily due to their semipermeable properties, enabling effective dialysis by filtering waste products from the blood.
