The reason why red blood cells don't pass through the dialysis tube is because red blood cells are too large to fit through the pores in the membranes but urea and salt flow through membranes into the sterile solution and are removed.
No, the blood cells are too large to pass through the dialysis membrane.
yes!
Artificial membranes in a dialysis machine are selectively permeable because it doesn't all cells to go through it. It doesn't allow blood cells to fit through the dialysis but it allows waste and bacteria to pass.
The dialysis membrane is selectively permeable because it doesn't allow all cells to go through it. Think of it as a kidney. When blood is sent to the kidney, the blood cells cannot fit through the dialysis inside the kidney, but the waste and bacteria in the cells do. So, The dialysis membrane is selectively permeable.
the urinary system
A dialysis machine tries to mimic some of the functions of a human kidney. One of the primary jobs of a kidney is to remove urea and certain salts from the blood so they can exit the body in urine. In a dialysis machine, blood from the patient runs through tubes made of a semi-porous membrane. Outside the tubes is a sterile solution made up of water, sugars and other components. Red and white blood cells and other important blood components are too large to fit through the pores in the membranes, but urea and salt flow through membranes into the sterile solution and are removed.
they are removed by your liver
No, red and white blood cells and platelets are not removed when urea is removed from the blood. Urea is a waste product that is filtered out by the kidneys, while the red and white blood cells and platelets are important components of the blood that perform essential functions in the body.
leucapheresis - blood is withdrawn through a vein and passed through a cell separator machine. white cells are removed and the rest of the blood is returned to the patient through another vein. this method can be usd to collect peripheral blood stem cells from a patient.
Both red and white blood cells pass through the capillaries.
YES
