Chapter 2, Problem 4AYKB
Summary Introduction
To review:
The working of a buffer system in maintaining the pH of body fluid when it increases. Also, determine whether it is an example of positive or negative feedback.
Introduction:
A buffer is a chemical system that balances the concentration of the hydrogen ions in case of excess acid or base. The buffer systems in the blood are extremely efficient in maintaining the blood and body fluid’s pH. Different systems work at different rates to regulate the pH.

What actually happens in the fluid compartments of your body when you are either extremely dehydrated and have drunk and extremely large amount of water. For both cases explain why these extremes are so dangerous,how the body will attempt to compensate and what might eventually be the cause of death.
Solutions conduct electricity, if there are charged particles or ions present. Our body contains ions, too. Thus, solution containing ions are called electrolytes. Why do you feel thirsty after playing or working outside? Sometimes, you suffer from cramps or headaches, in extreme cases, you may even experience vomiting and nausea. These are symptoms of electrolyte imbalance in the body. Suggest ways or recommendations that can be given to a person who experience electrolyte imbalance.
It is important to maintain optimal pH in the extracellular fluid otherwise illness and death can occur. Explain the mechanisms via which a pH level outside of homeostatic range negatively affects body function.

- The Respiratory System and Urinary System work hand-in-hand to maintain blood pH. Depending upon the cause, each system will utilize mechanisms to increase or decrease pH levels. Sometimes, one system works sufficiently to alleviate the acidosis or alkalosis. At other times, both systems will work together to bring pH levels within normal range. Compensation is the term used to describe how one system assists the other in normalizing blood plasma pH. Respiratory compensation works quickly, using brainstem respiratory centers to eliminate or retain CO2 levels in the blood and works more quickly. Renal compensation takes more time, changes HCO3- levels and generally has a greater ability to restore normal pH values. Based on the information given for each of the cases below, indicate whether there is an alkalosis or acidosis present. Assume that appropriate time has lapsed to cause the lab results listed. 1.
