True
True or False: Stress can be defined as a threat to homeostasis.
True
Antidiuretic hormone secretion may increase during physiologic stress leading to an increase in -blood sugar -urine output -serum sodium -body fluid volume

Allostatic adaptation in response to stress may be considered successful when -when hormones are no longer secreted. -heart rate falls below 100 beat/min. -homeostasis is restored. -the stress is no longer present.
homeostasis is restored
