What does Osmotically mean?

[oz-mo´sis, os-mo´sis] the diffusion of pure solvent across a membrane in response to a concentration gradient, usually from a solution of lesser to one of greater solute concentration.

What is hyper osmosis?

Hyperosmotic (biology definition): (1) of, relating to, or characterized by an increased osmotic pressure (typically higher than the physiological level); (2) a condition in which the total amount of solutes (both permeable and impermeable) in a solution is greater than that of another solution.

What does hypo osmotic mean?

– Hypo-osmotic: solution that exerts less pressure, lower concentration. of particles. – Hyperosmotic: solution that exerts more pressure, higher. concentration of particles.

What is osmotic water?

Osmosis is a special type of diffusion, namely the diffusion of water across a semipermeable membrane. Water readily crosses a membrane down its potential gradient from high to low potential (Fig. 19.3) [4]. Osmotic pressure is the force required to prevent water movement across the semipermeable membrane.

What does osmotic mean in medicine?

Listen to pronunciation. (oz-MAH-tik) Having to do with osmosis (the passage of a liquid through a membrane from a less concentrated solution to a more concentrated one). This causes the more concentrated solution to become diluted, and makes the concentrations in both solutions more equal.

What is an osmotic drug?

]. Osmotic drug-delivery systems suitable for oral administration typically consist of a compressed tablet core that is coated with a semipermeable membrane coating. This coating has one or more delivery ports through which a solution or suspension of the drug is released over time.

What does hyper and hypotonic mean?

Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood.

What is osmotic action?

1 : movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
