What is the role of osmosis in the dialysis process?
A
Osmosis increases the concentration of solutes in the blood during dialysis.
B
Osmosis facilitates the active transport of ions across the dialysis membrane.
C
Osmosis helps in the removal of waste products by allowing water to move across the dialysis membrane.
D
Osmosis prevents the movement of solutes across the dialysis membrane.
Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the role of osmosis in dialysis: In dialysis, osmosis helps in the removal of waste products by allowing water to move across the dialysis membrane, carrying waste products with it.
Clarify the function of the dialysis membrane: The dialysis membrane is semipermeable, allowing only certain molecules, such as water, to pass through while retaining larger molecules like proteins and blood cells.
Differentiate between osmosis and active transport: Osmosis is a passive process that does not require energy, whereas active transport involves the movement of ions or molecules against a concentration gradient and requires energy.
Recognize the incorrect statements: Osmosis does not increase solute concentration in the blood, facilitate active transport, or prevent solute movement; instead, it aids in waste removal by water movement.
