water /wa·ter/ (waw´ter) (wah´ter) 1. clear, colorless, odorless, tasteless liquid, H2O. 2. an aqueous solution of a medicinal substance; called also aromatic w. 3. purified w. bound water water in the tissues of the body bound to macromolecules or organelles. distilled water water purified by distillation. free water that portion of the water in body tissues which is not bound by macromolecules or organelles. water for injection water for parenteral use, prepared by distillation or reverse osmosis and meeting certain standards for sterility and clarity; it may be specified as sterile if it has been sterilized and as bacteriostatic if suitable antimicrobial agents have been added. purified water water obtained by either distillation or deionization; used when mineral-free water is required.
water (H2O) [wô′tər] Etymology: AS, waeter a chemical compound, one molecule of which contains one atom of oxygen and two atoms of hydrogen. Almost three quarters of the earth's surface is covered by water. Essential to life as it exists on this planet, water makes up more than 70% of living things. Pure water freezes at 32° F (0° C) and boils at 212° F (100° C) at 760 mm Hg. water, n one of the five phases, or elements, in Chinese cosmological and medical theory, the characteristic manifestations of which include anxiety, introspection, mystery, ner-vousness, philosophical speculation, solitude, and truthfulness. water, aromatic, n fluid prepared in a laboratory by combining distilled water with any number of essential oils; may also comprise some artificial and synthetic ingredients and in some cases, alcohol. water, essential, n the end product of the process in which steam is passed through plant material to derive the benefits of the plant's essence. water, floral, n the residual water from distillation carried out to extract essential oils from plant material, considered therapeutically useful and used in skin care and perfumery industries. Also called hydrosol. water, hamamelis (hamˑ· n liquid infused with an extract from Hamamelis virginiana twigs for use as an astringent. Also called witch hazel. water, memory of, n the theoretical ability of water or water-ethanol mixes to carry information during dilution and succession. water, prepared, n a product containing any number of natural and artificial ingredients; meant to resemble plain water. water, smart, n theoretically, a solvent (typically water) that retains the information imprinted by the substance(s) dissolved in it. Used by some to explain the mechanism through which homeopathic remedies work. water, n a tasteless, odorless, colorless compound made of hydrogen and oxygen (H2O), which freezes at 32°F (0°C) and boils at 212°F (100°C). The autonomic nervous system regulates water balance in the body. water depletion, n cellular dehydration through decreased water intake, dysphagia, excessive sweating, and diuresis. water, distilled, n a type of purified water that has undergone evaporation and recondensation prior to bottling. water need, n the amount of water needed to maintain metabolism, approximately 1000 ml/day. water, superoxidized n an electrolyzed saline solution used as a disinfectant. water syringe, n See syringe, water. water 1. a clear, colorless, odorless, tasteless liquid, H2O. 2. an aqueous solution of a medicinal substance. water bag see waters. water blanket a sheet with water-filled channels through which heated water is circulated by an external pump. This is placed beneath an anesthetized patient to maintain body temperature during surgery and avoid hypothermia. body water see total body water. body water loss is principally through the urine, supplemented by sweating, fecal water and evaporation in expired air. water-damaged grain recorded as toxic due to tunicamycin in mixture produced probably by fungi. water deprivation the animals are cut off from any source of water. May be by accident or neglect. water deprivation syndrome the animals become frenzied and begin to destroy their surroundings in an attempt to find water. There is abdominal gauntness, sunken eyes and weakness, and abortion may occur later. water deprivation test a test of the concentrating ability of renal tubules and their responsiveness to endogenous antidiuretic hormone. Urine specific gravity and/or osmolality is measured before water is withheld, at intervals during, and after an average time period of 12 to 24 hours. The normal animal should produce urine that is progressively more concentrated, with an osmolality becoming greater than that of the plasma. distilled water water that has been purified by distillation. water drowning a primitive method of euthanasia, especially for unwanted, newborn animals. water-electrolyte balance the concentration of individual electrolytes and of groups of, e.g. monovalent electrolytes, in serum, in tissue fluids and in intracellular fluid is critical to normal bodily function and is maintained by variation in the renal excretory rate of each electrolyte. water homeostasis conservation of body water during times of deprivation or excessive loss due to diarrhea or heavy sweating is effected by an increase in the concentration of the urine by the renal tubules. water immersion prolonged head-out water immersion has been used in the treatment of skeletal injuries in horses because of the weightlessness induced but there are serious implications of osteoporosis. water intoxication can occur if very thirsty animals, on limited salt intake, are allowed unlimited access to water. There is tremor, incoordination and convulsions and there may be polioencephalomalacia. Hemoglobinuria and hypothermia may also occur. water loading test measures the concentrating power of the kidney by combining the water deprivation and ADH tests. water marker a substance injected into the body that will diffuse through all of the body water compartments. The reduction in its concentration after injection can be used as a measure of body water. Tritiated water is used for the purpose. water marker decay curve the curve of declining concentration of a water marker in intravascular fluid. water medication administration of medication in drinking water is used particularly in birds and also in swine. water provocative test measurement of intraocular pressure before and after the administration of a large volume of water by stomach tube. A marked increase occurs in glaucomatous eyes. water salinity see sodium chloride. water seed see hydrocele. water vapor partial pressure in humans is the same in venous and arterial blood, in pulmonary alveolar air and in tissues; it is assumed that the same generalization applies to animals. water H2O A colorless liquid critical for biologic reactions See Bottled water, Drinking water, Finished water, Fluoridated water, Hard water, Heavy water, Hydrotherapy, Individual water, Mineral water, Musket shot water, Raw
water, Reagent grade water, Soft water, Source water, Spring water, Surface water. Patient discussion about watered. Q. Is drinking too much water harmful? Is there a condition like “water overdose”? A. Drinking more water then you are used to is very good for you. But of course if you over do it it’s damaging. Drinking way too much will make you urinate more, this means you will also loose vital minerals in the urine like potassium and sodium. This can even lead to death. http://chemistry.about.com/cs/5/f/blwaterintox.htm http://www.msnbc.msn.com/id/16614865/ Q. How does drinking a lot of water before an activity helps to avoid dehydration? Question Description It just makes me go to the bathroom more… A. you need to drink water before,during and after any sports or exercises,because you sweat which causes dehydration. Q. My dad was just burned from hot water what should he do to ease the pain? My dad had just spilled hot tea on his thigh. Is there anything we can do to ease his pain? should we go to the hospital? A. To ease the pain your dad can take some kind of NSAID (if he is not allergic to them of course) - though it's better to consult his doctor or the pharmacist. you can also take a wet towel and put it on the burned area. more important is that if its very painful or if it has blisters or if the burn is on the genitalia area - go to see a doctor because there is a risk (small risk but still) for serious damage.
