isotonic [i″so-ton´ik] 1. of equal tension.2. denoting a solution in which body cells can be bathed without net flow of water across the semipermeable cell membrane; also, denoting a solution having the same tonicity as another solution with which it is compared.i·so·ton·ic (ī'sō-ton'ik), 1. Relating to isotonicity or isotonia. 2. Having equal tension; denoting solutions possessing the same osmotic pressure; more specifically, limited to solutions in which cells neither swell nor shrink. Thus, a solution that is isosmotic with intracellular fluid will not be isotonic if it includes solute, such as urea, that freely permeates cell membranes. 3. In physiology, denoting the condition when a contracting muscle shortens against a constant load, as when lifting a weight. Compare: auxotonic, isometric (2). isotonic (ī′sə-tŏn′ĭk)adj.1.

Compare: auxotonic, isometric (2) isotonic Of a fluid that exerts the same OSMOTIC PRESSURE as another, especially as that of the body fluids. Body cells, such as red blood cells, can be immersed in an isotonic solution without being caused to change shape. ‘Normal’ saline is isotonic with blood.isotonic (of a liquid) having a fluid state with the same WATER POTENTIAL as another liquid.
