GENERAL HISTOLOGY

Detailed explanation-1: -Fluid is pumped into the peritoneal cavity through the catheter. As blood passes through the blood vessels lining the peritoneal cavity, waste products and excess fluid are drawn out of the blood and into the dialysis fluid. The used fluid is drained into a bag a few hours later and replaced with fresh fluid.

Detailed explanation-2: -Ultrafiltration in Hemodialysis 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-3: -Haemodialysis process During dialysis, 2 thin needles are inserted into the arteriovenous fistula. One needle removes blood and transfers it to a machine called a dialyser. The machine filters the waste products from the blood. Filtered blood is passed back into the body through the second needle.
