waste materials that have toremoved by kidneys.
Red blood cells and plasma proteins are not removed during dialysis because the dialysis process is designed to filter out waste products and excess substances from the blood while retaining larger elements essential for health. The semipermeable membrane used in dialysis allows small molecules and waste to pass through but blocks larger components like red blood cells and proteins. This selective filtration helps maintain the necessary balance of blood components while effectively clearing toxins and excess fluids.
I think they must be removed by a dialysis machine.

during dialysis the blood is is flowin through a closed system
The membranes in a dialysis machine are selectively permeable, meaning they allow certain substances to pass through while blocking others. This selectivity allows toxins and waste products to be removed from the blood while retaining essential substances.
During dialysis, the process aims to remove waste products and excess fluids from the blood when the kidneys can no longer perform this function. Red and white blood cells are typically not removed because they are essential components of the blood that perform critical functions, such as oxygen transport and immune response. However, if blood is exposed to the dialysis membrane or if there is a malfunction in the dialysis process, there could be some unintended loss of these cells. Properly functioning dialysis systems are designed to selectively remove waste while preserving blood cells.
yes!
Keep the concentration of these substances in the dialysis fluid same as in the blood, and they won't diffuse out.
Dialysis is a medical procedure that removes waste products and excess fluids from the blood when the kidneys are unable to perform this function. During dialysis, blood is drawn from the body and passed through a dialysis machine, where it is filtered through a semipermeable membrane. This membrane allows waste substances and excess electrolytes to pass out of the blood while retaining necessary components like red blood cells and proteins. The cleaned blood is then returned to the body, helping to maintain electrolyte balance and regulate blood pressure.
Toxins and waste are filtered from the kidneys
There are two methods of dialysis in use: hemodialysis (blood dialysis) and peritoneal dialysis (dialysis in the abdominal cavity). In hemodialysis, the dialysis membrane is made up of cellophane or other synthetic material that assists in the removal of impurities from the blood by their passage through these semipermeable membranes in a fluid bath. In peritoneal dialysis, the surface area of the peritoneum acts as the membrane. Dialysis fluid is introduced into the peritoneal cavity and then periodically removed along with the waste products. This procedure may be done at intervals throughout the day or during the night.
