LECTURE OBJECTIVES (Instructional goals)

AT THE END OF THIS CHAPTER, YOU SHOULD BE ABLE TO:
1. Understand how the human body maintains a rather constant internal environment despite changing external conditions.
2. Know the components and mechanism of homeostasis, and use temperature regulation to describe the mechanism.
3. Define and discuss negative and positive feedback mechanisms.
4. Describe a reflex arc. (This is in the nervous system chapter, and may not be required all semesters.)
5. Define selected key terms (see textbook).
