Homeostasis Webquest – Ben’s Bad day!

Homeostasis is the ability to maintain a constant internal environment in response to environmental changes. It is a unifying principle of biology.

The nervous and endocrine systems control homeostasis in the body through feedback mechanisms involving various organs and organ systems. Examples of homeostatic processes in the body include temperature control, pH balance, water and electrolyte balance, blood pressure, and respiration.

You are going to follow Ben on through his day his to determine why is responding to his environment the way he is.

Begin by going to http://ats.doit.wisc.edu/biology/lessons.htm

Click on the “Homeostasis” link in the Animal Physiology box

After reading this page, click on topic 1 “Ben’s Bad Day”  Go thru Ben’s day starting at 8:00 am and ending at 12:00 am and answer the questions below

1. Why did Ben feel dizzy and faint when he jumped out of his chair?

2. List the steps Ben’s body must go thru to maintain homeostasis.  Be sure to identify the parts of the body involved and what they did.

3. What stimulus did Ben’s body have to deal with at 8:30?

4. List the steps Ben’s body must go thru to maintain homeostasis.  Be sure to identify the parts of the body involved and what they did.

5. What did Ben’s muscles produce when he ran after his paper at 11:50 am?

6. What impact did this have on the pH of his blood?

7. Which organ did Ben’s nervous system stimulate to help maintain homeostasis? How was pH balanced
restored.

8. During his Biology test, Ben’s brain needs more glucose, what do the adrenal glands release and where do they go to help increase Ben’s glucose level

9. At 8:30 Ben eats some pretzels.  What does this do to his blood chemistry? What does this mean?

10. What happened next in Ben’s bodys attempt to restore homeostasis?

11. What organ was stimulated by the above action by Ben’s body? What was its response?

12.  What did Ben do to increase his glucose level?

13. How does Ben’s body respond to the increased glucose level?

14.  Which part of Ben’s body is stimulated to take up the excess glucose?

15 What other parts of Ben’s body work to maintain homeostasis in the above situation? 

16. What part DOES NOT assist in this process and why?

Scroll to the bottom of the page and click the arrow indicating the next page. Read this page and answer the questions below. 
 
17.  Which body messenger service is most like email?   Most like “snail mail”?

18.  What are the messenger molecules used by the nervous system?  The endocrine system?

Click on the arrow at the bottom of the pages to continue thru this section of the webquest.

19. Describe the path that the neurotransmitter took to increase Ben’s blood pressure.

20.  Describe the path that the hormones took to regulate Ben’s glucose level.

21.  Can both the endocrine and the nervous system work together to maintain Homeostasis? Give an example from Ben’s bad day in which both systems played a part.

22. Which system kicked in first?

23.  What part of the endocrine system was stimulated, what hormone was released, where did it go, and what was the target cell’s response?            
 
24.  Read the want adds below and determine if Neurotransmitters or hormones are best suited for the job?
