Directions: In this module, we explored the idea of the pH scale and the importance of maintaining the pH of a given environment for the overall functioning of organisms that inhabit that environment. For this discussion, identify one area within your own body, nature, or another organism where maintaining pH is important for overall functioning in that organism's environment. You may want to review the general concept of homeostasis before writing your post.

To receive full credit for this discussion, include a definition for homeostasis in your own words and explain the environment you chose as one where maintaining pH is critical for functioning.  Also include any "fail safes" that may be in place to maintain the pH in this environment. You will want to pick a unique situation and one that is different from your classmates' to receive full credit.
