| distilled water | Water purified by distillation. (05 Mar 2000) |
| indifferent water | A mineral water containing only a small quantity of saline matter. (05 Mar 2000) |
| ordinary high water mark | <marine biology> That line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of the soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas. (11 Jan 1998) |
| tar-water | A cold infusion of tar in water, formerly regarded as a cure-all. (webster, 3d ed) (12 Dec 1998) |
| earthy water | A water containing a large amount of mineral matter, chiefly sulfate, in solution. (05 Mar 2000) |
| total body water | The sum of intracellular water and extracellular water (volume). About 60% of body weight. (05 Mar 2000) |
| transcellular water | That fraction of extracellular water in cerebrospinal, digestive, epithelial, introcular, pleural, sweat, and synovial secretions; about 1.5% of body weight. (05 Mar 2000) |
| extravascular lung water | <physiology> Water present within the lungs; its volume is roughly equal to, or a little less than, the intracellular blood volume of the lungs. Accumulations of extravascular lung water result in pulmonary oedema. (12 Dec 1998) |
| free water | Water in the body that can be removed by ultrafiltration and in which substances can be dissolved. (05 Mar 2000) |
| free water clearance | The amount of water excreted in the urine beyond that which would accompany the excreted solutes if the urine were isosmotic with plasma; it represents the loss of body water in excess of solute tending to raise body osmolality and making urine hyposmotic. Unlike other clearance's, it is calculated by subtracting the osmolal clearance from the actual volume of urine excreted per minute. A negative value for free water clearance represents the amount of water that the body has reclaimed from isosmotic tubule fluid to make the urine hyperosmotic and to lower body osmolality.
