Definitions:

Extracellular Fluid

Fluid that exists outside the cells of an organism, including blood plasma, lymph, and interstitial fluid, providing a medium for transport of nutrients and waste.

Solute Concentration

The amount of a substance dissolved in a unit volume of solution, often referred to in terms of molarity, molality, or mass percent.

Hypertonic

A Hypertonic solution is one in which the concentration of solutes is greater outside the cell than inside it, leading to cell shrinkage.

Osmotic Pressure

Osmotic pressure is the pressure that must be applied to a solution to prevent the inward flow of water across a semipermeable membrane, driven by differences in solute concentration.
