Except in some of the lower orders, virtual constancy of the volume of body water is a prerequisite for the normal function and indeed the survival of the organism. In terrestrial animals, particularly, adaptive mechanisms provide for physiological regulation of the amounts of water which leave and enter the body. Although solid foods provide a considerable quantity of pre-formed water to the b...
Using intravenous infusion, we separated the physiologic consequences of 3% body mass dehydration from the conscious awareness of fluid replacement on time trial (TT) performance in the heat. Eleven trained cyclists performed 90 min of steady-state (50% V ˙ O 2 peak ) cycling followed by a self-paced 20-km TT in a hot-dry (35 °C, 10% relative humidity, wind speed 3.0 m/s) environment while euhy...
The Thirst centres on the struggle of three shipwreck victims to survive a small white raft adrift glassy sea. Descending into madness as result their thirst, they prey each other until sacrifice humanity uncaring, black-stained Despite common predicament, are separated by social, well psychological, forces. Dancer is called young from stage direction play. ONeill described her figure pitiful c...
The Bischof-Köhler hypothesis posits that nonhuman animals cannot plan for future motivational states that differ from a current state. [Naqshbandi, M., Roberts, W.A., 2006. Anticipation of future events in squirrel monkeys Samiri scireus and rats Rattus norvegicus: tests of the Bischof-Köhler hypothesis. J. Comp. Psychol. 120, 345-357] found that two squirrel monkeys that were not thirsty at t...
Increased dietary salt intake was used as a nonpharmacological tool to blunt hypotension-induced increases in plasma renin activity (PRA) in order to evaluate the contribution of the renin-angiotensin system (RAS) to hypotension-induced thirst. Rats were maintained on 8% NaCl (high) or 1% NaCl (standard) diet for at least 2 wk, and then arterial hypotension was produced by administration of the...
We investigated urinary changes and thirst induced by infusion of hyperosmotic solutions in freely moving rats. Intracarotid infusions of 0.3 M NaCl (4 ml/20 min, split between both internal carotid arteries) caused a larger increase in excretion of Na(+) and K(+) than intravenous infusions, indicating that cephalic sensors were involved in the response to intracarotid infusions. Intravenous an...
Associations between hunger and eating and between thirst and drinking are generally weak. This stems, in part, from limitations in the measurement of these sensations which generally rely on temporal, motivational, metabolic and/or self-reported descriptive indices. Each is critically reviewed. Also problematic is the fact that the deterministic depletion-repletion concept of ingestive behavio...
The instinct of thirst was a cardinal element in the successful colonization by vertebrates of the dry land of the planet, which began in the Ordovician period about 400 million y ago. It is a commonplace experience in humans that drinking water in response to thirst following fluid loss is a pleasant experience. However, continuing to drink water once thirst has been satiated becomes unpleasan...
