Homeostasis

Hello Health Students!
I hope you are all having a great day!  This time of year, many people feel a lot of stress.  How do you handle stress?  Today we are going to talk about how your body keeps itself in balance.

The process by which the body's internal environment is kept stable in spite of changes in the external environment is called homeostasis.  An example of your body maintaining it's internal environment is that, no matter what the outside air temperature is, your body maintains it's internal temperature as close to 37 degrees Celsius, as long as you are healthy. ( If you are sick, your body may not be able to maintain this temperature, until you become well again.)


1.  Can you think of other ways your body maintains homeostasis?  List ways that you can think of, then do a bit of research and see if you can find more.  List any other ways that you find during your research.

Stress can disturb homeostasis and cause changes in the body. Think about a time when you were stressed.  2. What changes do you notice happen to you when you are feeling stressed?

3.  Look up these terms and tell me how they are involved in dealing with stress.
          adrenaline
          fight or flight
4.  Interpreting Data

A scientist fed a strong sugar solution to an animal.  The scientist then checked the concentration of sugar in the animal's blood during the next three hours.  The table below shows the results of the experiment.
Explain how the data show homeostasis at work.  ( Hint: Think about what happened to the blood-sugar level during the first hour and then during the next two hours)



Time after eating sugar                 Sugar concentration ( milligrams/100 millileters)
( minutes)

5.  What are three helpful ways of dealing with stress?  How do you usually deal with stress?

6.  The three components of wellness are physical health, mental health and social health.  Please describe what each of these are.
