3. Homeostasis Learning Goals
I can explain the meaning of homeostasis & dynamic equilibrium
I can describe 4 examples of homeostasis in the human body
I can explain how organ systems use negative feedback to maintain homeostasis
I can apply and extend examples of homeostasis using graphs and diagrams

4. PRACTICING PREDICTING…
Create a hypothesis
What do you think a graph of maintaining body temperature will look like?
Can you explain
Using sci. language?
-dynamic equilibrium
-vasoconstrictioN
-vasodilation

5. PracticE Analyzing & ApplYIng
Q1. how DOES this example illustrate the general principle that "Positive feedback is useful when there is an advantage to making a rapid change.“? Q2. What would go wrong if your body used positive feedback to regulate body temperature?

7. Practice AP Exam free Response Q
Homeostatic maintenance of optimal blood glucose levels has been intensively studied in vertebrate organisms. a) identify TWO pancreatic hormones and describe the effect of each hormone on blood glucose levels. (b) For ONE of the hormones you identified in (a), identify ONE target cell and discuss the mechanism by which the hormone can alter activity in that target cell. Include in your discussion a description of reception, cellular transduction, and response
