    isoosmotic solution

    Definition "solution that exerts the same pressure (i.e. has the same concentration of particles, the same osmolarity) as another on a membrane that separates them" Reference "COM-Terminology Coordination, based on: Rob MacLeod. 'Osmotic Balance' (9.4.2021). Bioengineering 6000 CV Physiology"
    Comment 1) isosmotic solutions are not always isotonic. Hyperosmotic solutions are not always hypertonic. But hyposmotic solutions are always hypotonic.2) Osmolarity and tonicity are related but distinct concepts. Thus, the terms ending in -osmotic (isosmotic, hyperosmotic, hyposmotic) are not synonymous with the terms ending in -tonic (isotonic, hypertonic, hypotonic). The terms are related in that they both compare the solute concentrations of two solutions separated by a membrane. The terms are different because osmolarity takes into account the total concentration of penetrating solutes and non-penetrating solutes, whereas tonicity takes into account the total concentration of non-freely penetrating solutes only.
