Explanation:
Detailed explanation-1: -In hemodialysis, fluid is removed by ultrafiltration using the dialysis membrane. The pressure on the dialysate side is lower so water moves from the blood (place of higher pressure) to the dialysate (place of lower pressure). This is how the hemodialysis treatment removes fluid.
Detailed explanation-2: -With hemodialysis one supplements calcium and bicarbonate, while removing potassium, magnesium, and urea and other toxins using diffusion. Water and sodium are removed by ultrafiltration.
