Animal physiologists study feedback systems that regulate various body functions, observing that most physiological regulation involves negative feedback that maintains stable conditions. What characterizes negative feedback in animal physiology?
Question 4 options:

Negative feedback systems only work when animals are completely healthy with no environmental stress

Negative feedback always makes physiological conditions worse for animal health and survival

Negative feedback counteracts changes to maintain stable physiological conditions through corrective responses

Negative feedback prevents animals from responding to any environmental changes or challenges

Correct answer:
Negative feedback counteracts changes to maintain stable physiological conditions through corrective responses.

Explanation: In negative feedback the system senses a deviation from a set point and initiates responses that reduce that deviation (e.g., sweating and vasodilation when body temperature rises; shivering and vasoconstriction when it falls; insulin lowering blood glucose after a meal).
