what is the basic difference between dialysis and osmosis?

1 Answer. Osmosis is the diffusion (i.e. movement) of a solvent (e.g. water) across a semi-permeable membrane. Dialysis is the separation (i.e. movement) of molecules themselves.

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.

Explanation: Simple diffusion is the movement of molecules from an area of higher concentration to lower concentration. ... Osmosis is the movement of water from an area of less concentration of dissolved particles to an area of high concentration, thus equalizing the concentrations on each side.

Peritoneal dialysis is done more continuously than hemodialysis, resulting in less accumulation of potassium, sodium and fluid. This allows you to have a more flexible diet than you could have on hemodialysis. Longer lasting residual kidney function.

"In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute." ... So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides.

Explanation: Osmosis involves water moving from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane. ... Put more simply, dialysis is the movement of molecules in solute (e.g. glucose) and osmosis is the movement of the solvent (water) itself.

One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

Osmosis is the diffusion (i.e. movement) of a solvent (e.g. water) across a semi-permeable membrane. Dialysis is the separation (i.e. movement) of molecules themselves.

Diffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane. Active transport moves particles from low to higher concentration.

The term osmolarity refers to the number of particles of solute per liter of solution, whereas the term osmolality refers to the number of particles of solute per kilogram of solvent. ... The measured osmolality should not exceed the calculated osmolality by more than 10 mOsm/kg.

There are two kinds of peritoneal dialysis: The basic treatment is the same for each. However, the number of treatments and the way the treatments are done make each method different. CAPD is "continuous," machine-free and done while you go about your normal activities such as work or school.

If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

Osmosis. Osmosis is a form of passive transport that's similar to diffusion and involves a solvent moving through a selectively permeable or semipermeable membrane from an area of higher concentration to an area of lower concentration.

Osmolarity refers to the number of solute particles per 1 L of solvent, whereas osmolality is the number of solute particles in 1 kg of solvent. For dilute solutions, the difference between osmolarity and osmolality is insignificant.

The key difference between ultrafiltration and selective reabsorption is that ultrafiltration is the process of filtering small molecules such as water, glucose, amino acids, sodium chloride and urea from blood to the glomerulus capsule due to the high hydrostatic pressure, while selective reabsorption is the process ...

There are two main types of dialysis, hemodialysis and peritoneal dialysis. Hemodialysis uses a machine and a filter to remove waste products and water from the blood. Peritoneal dialysis uses a fluid (dialysate) that is placed into the patient's abdominal cavity to remove waste products and fluid from the body.
