★ Must-know
Further detail
1. What does homeostasis describe?
2. A person’s body temperature fluctuates slightly during the day but remains within a normal range. Which principle does this illustrate?
3. A rise in a regulated condition triggers a response that reduces that rise and moves the condition toward its set point. What type of feedback is occurring?
What is homeostasis?
The maintenance of a relatively stable internal environment despite changes in the body or its surroundings.
What is the body-temperature set point, and how is temperature regulated?
The set point is about 37°C, and temperature is regulated within a normal range.
What does negative feedback do to the initial stimulus?
It opposes the initial stimulus.
What follows the stimulus in a feedback system?
A response that affects the regulated condition.
It covers the core concepts of Homeostasis and Feedback Systems, organized by topic with the key definitions, explanations and takeaways, so it's easier to learn and remember.
