What involves the movement of solutes across a selectively permeable membrane by the process of difussion?
facilatated diffusion
What substances in the blood pass through the partially permeable membrane into the kidneys?
As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
What ways is a dialysis membrane functionally similar to a plama membrane?
They are both semipermeable allowing certain things to pass though membrane and other not to pass through membrane.
Type of tubing that is semi-permeable?
The type of tubing that is semi-permeable is that tubing used for dialysis. It needs to be semi-permeable to switch or remove molecules for different types of diffusion.
What will happen when starch is mixed with solutions?
In this scenario, the concentration of solutes (the glucose and starch) is higher inside of the dialysis tubing than it is outside. As such, water will diffuse (via osmosis) into the dialysis tubing causing it to swell.
What process does dialysis use active transport simple diffusion or facilitated diffusion?
If your talking about a high concentration (outside the dialysis bag) to low concentration (inside the dialysis bag), then it's simple diffusion because it does not requires any energy, and not facilitated in any way
Why does the fluid in dialysis have to flow in opposite directions?
It has to flow in opposite directions to keep a balanced concentration therefore a balanced diffusion. If it went in the same direction as the blood there would be less diffusion as, for instance, by the time the dialysis fluid from the right side got the the left, no more diffusion could take place with the blood above it as the fluid would already have gone though diffusion with blood further back down the right end so particles would not move from a high concentration to a low concentration as the fluid below would have a high concentration too from what it gained back at the right end.
Is dialysis osmosis or diffusion?
Dialysis is the separation of particles in a liquid on the basis of differences in their ability to pass through a membrane. As a semi permeable membrane is involved, so it is an osmosis.
What are the principal cations in opur body fluids?
Well, considering this isn't even a full sentence, let alone a question, I'll see what I can pull out of it.Diffusion of a substance across a semipermeable membrane is diffusion.Diffusion of a solute across a semipermeable membrane is dialysis.Diffusion of water across a semipermeable membrane is osmosis.Diffusion is a type of passive transport.Osmosis and dialysis are both forms of diffusion.
How do osmosis and dialysis releate to diffusion?
Osmosis is the the diffusion of water or any soluble liquid across a semipermeable membrane such as the outer membrane of a cell. When water moves out of the cell faster then the intake of water, the cell will shrink. This is a hypertonic solution. When the intake is greater than the output, the cell will grow. This is a hypotonic solution. When a balance is achieved, water moving equally in and out of the cell, an isotonic solution is created. Dialysis is when the kidney allows only certain things to DIFFUSE through it. For example, a biology class put an egg in a vinegar solution. This causes the egg to grow because the vinegar was at a higher concentration then the inside of the egg and biology states that it will flow from a high concentration to low concentration. When that same egg is placed in water, the vinegar flows out of the egg because the water was a lower solution of vinegar than the egg. So all of this comes down to the fact that in both osmosis and dialysis, something is being diffused through the cell's semipermeable membrane. If you need a clearer explanation, ask you school's biology teacher(s).
Which process is involved in dialysis process?
diffusion
What does dialysis separate?
the separation of disolved molecules based on their ability to pass through a semipermeable membrane.
What is dialysis catheter?
A dialysis tube is a semipermeable membrane that allows molecules of a certain size to get in or out, while keeping molecules above that size in. They are often used to remove impurities from preparations of proteins or other macromolecules, or to normalize pH of a preparation.

What is the physical principle upon which kidney dialysis is based on?
Diffusion
How do you separate particles of a colloid?
By dialysis
What process do chemical wastes pass from the blood into the dialysis fluid?
