balance

 [bal´ans]
an instrument for weighing.
equilibrium (def. 1).
acid-base balance see acid-base balance.
analytical balance a balance used in the laboratory, sensitive to variations of the order of 0.05 to 0.1 mg.
fluid balance see fluid balance.
negative balance a state in which the amount of water or an electrolyte excreted from the body is greater than that ingested.
nitrogen balance see nitrogen balance.
positive balance a state in which the amount of water or an electrolyte excreted from the body is less than that ingested.
water balance fluid balance.
zero balance a state in which the amount of water or an electrolyte excreted from the body is exactly equal to that ingested; see equilibrium (def. 1).

water balance

A state of equilibrium in which the fluid intake from water and other beverages and foods equals fluid losses in the gastrointestinal tract, urine, sweat and other secretions.

water balance

A state of equilibrium in which the fluid intake from water and other beverages, and foods equals fluid lost in the urine, GI tract, sweat, and other secretions. See Water.

balance

1. an instrument for weighing.
2. harmonious adjustment of different elements or parts; harmonious performance of functions. Used to describe symmetry and proportion of conformation.

acid-base balance
the proportion of acid and base required to keep the blood and body fluids neutral. See also acid-base balance.
analytical balance
a laboratory balance sensitive to very small variations of the order of 0.001 mg.
balance examination
simultaneous palpation of muscles on both sides of the body of Greyhounds attempting to locate areas of soreness or spasm.
fluid balance
the state of the body in relation to ingestion and excretion of water and electrolytes (see also fluid balance).
nitrogen balance
the state of the body in regard to ingestion and excretion of nitrogen. In negative nitrogen balance the amount of nitrogen excreted is greater than the quantity ingested. In positive nitrogen balance the amount excreted is smaller than the amount ingested. See also nitrogen balance.
posture balance
disturbances of balance, including falling to one side, rotation of the head, walking in circles. These are usually indications of disturbances of the organs of balance in the semicircular canals.
water balance
fluid balance.
