Detailed explanation-1: -Before starting peritoneal dialysis, a catheter is inserted into the abdominal cavity. The catheter allows you to put the dialysis fluid into your abdomen yourself. Any harmful substances will then diffuse into the dialysis fluid from the blood vessels in the peritoneum.
Detailed explanation-2: -Dialysis involves the removal of solutes across a semipermeable membrane down the concentration gradient by two mechanisms: Diffusive clearance due to random molecular motion. Small molecules have a higher rate of diffusive transport through the membrane.
Detailed explanation-3: -Water is removed by ultrafiltration (JUF) from the plasma compartment, and small solutes are removed by diffusion and convection by the dialyzer.
Detailed explanation-4: -Dialysis is a separation process in which concentration gradient works as a driving force to separate solute and solvent. Due to the concentration difference, diffusion arises and solute passes across the membrane. Unlike pressure-driven process, this process is slow.
