Document Summary

Solvent and ionizing powers ideal for dispersal of organic and inorganic molecules facilitation of cell reactions. Opposes pulmonary inflation (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Facilitates digestion, transport, and excretions of other nutrients. Intimately involved in many biochemical reactions as a reactant (cid:1) (cid:1) and metabolites (cid:1) (cid:1) or product. Total body water content is closely/inversely related to body fat content (aka incr. fat content = decr. water content: implies that body water content is a good predictor of. Water content of lean body tissues is relatively constant at body fatness. Water metabolism and requirements: not dependent on age or body fatness. More body water is contained in intracellular fluid (60-70%) than in extracellular fluid (30-40%) Body water turnover is usually directly related to body water content: factors affecting water content and turnover = genotype, age, environmental temperature, feed quantity and quality, physiological state. Water balance = water supply water loss.
