How does behavior factor into the maintenance of fluid/electrolyte homeostasis? Behavioral responses are critical in signaling physiological changes Behavioral responses are critical in restoring normal state (esp. when ECF volume decreases or osmolarity increases) Behavioral responses are critical in restoring normal state (esp. when ECF volume increases or osmolarity decreases) Behavioral responses are stimulated by oropharynx receptors which respond to cold water by decreasing thirst QUESTION 11 Match the osmolarity changes and how specific cell types respond to address osmolarity challenges. v ECF osmolarity increases (e.g., salt intake) A. little to no net movement of water into/out of cells + cells v ECF osmolarity decreases (e.g., excess water intake) stay the same size/shape B. ECF osmolarity stays the same (e.g., normal, balanced water moves out of cells + they shrink water and salt intake) C. water moves into cells + they swell
