NEET PG DENTAL EXAM

Detailed explanation-1: -Osmosis. Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane.

Detailed explanation-2: -The blood and dialysis fluid are separated only by a thin wall, called a semipermeable membrane. This membrane allows particles that the body needs to get rid of to pass through it, but doesn’t let important parts of the blood (e.g. blood cells) pass through.

Detailed explanation-3: -Cell membranes are an example of semi-permeable membranes. Cell membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through, but do not allow larger molecules like sucrose, proteins and starch to enter the cell directly.

Detailed explanation-4: -Diffusion dialysis (DD) is an ion-exchange membrane (IEM) separation process driven by concentration gradient and has been applied for separation and recovery of acid/alkali waste solutions in a cost-effective and environmentally friendly manner.
