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. For each case, indicate whether the cause is…
When a dehydrated human patient needs to be given fluids intravenously, he or she is given: a. water, which is hypotonic with respect to body fluids b. saline at a concentration that is isotonic with respect to body fluids c. glucose because it is a non-electrolyte d. blood
Water concentration in the body is critical for proper functioning. A person’s body retains very tight control on water levels without conscious control by the person. Watch this video (http://openstaxcollege.org/l/H2Ocon) to learn more about water concentration in the body. Which organ has primary control over the amount of water in the body?

- 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.arrow_forwardA "red-hot" bacteria infection of the intestinal tract irritates cell and interface with digestion.

- An American woman, Jennifer Strange, died in 2007 after competing in a water-drinking contest. She drank six liters of water in three hours in a radio station's contest titled "Hold Your Wee for a Wii (Nintendo Game Console)." After the event, she vomited, experienced a terrible headache, and died due to water intoxication. Studies show that drinking too much water can be detrimental to one's health as much as drinking too little. Explain how can drinking too much water be harmful.arrow_forwardDescribe the feedback process that would occur if you drank far more water than your body needed.arrow_forwardAppropriate water balance in our body is important to support vital functions.

One problem is that people may not realize how much water they are losing through sweating.
