10. What are the 5 most important electrolytes?
Na, Cl, K, Mg, sulfate, phosphate, and HCO3.
7. Where is the thirst center located?
11.What are the 3 most important electrolytes.
Na, K, and Ca are the most important positively charged.
3. What are the major electrolytes found in extracellular fluid?
The most important electrolytes are Na, Cl, K, Mg, sulfate, phosphate, and HCO3. most electrolytes are obtained from food
14. Complete this reaction:
CO2+H2O---->_________-----> _____+________.
H2CO3-----> H + HCO3 (aerobic respiration of glucose)
8. What is normal water output per day, what % is urine, feces, sweat, and lungs/skin?
urine - 60 %
feces - 6 %
sweat - 6 %
lungs/skin - 28 % due evaporation, called insensible water loss
12. What effect does aldosterone have on sodium?
Sodium reabsorption is increased by akdisteribe.
1 What is the total water % found in females & males?
52% water volume can be found in females.
63% water volume can be found in males.
13. What is the most important/abundant positively charged electrolyte found in extracellular fluids?
Na = 90% of the positively charged ions.
6. What is normal water intake per day? What 3 ways contribute to this water intake and what percentages do they comprise?
Drink, 60%, food 30%, metabolism 10%, the daily intake is 2500 ml's a day.
9. What is meant by insensible water loss?
Evaporation of water through the skin and lungs.
2. What are the two major fluid compartments? What % water is found in each?
Intracellular compartment - 63% of the total water is within the cells.Extracellular compartment - all fluids outside the cells.

4. What are the major electrolytes found in intracellular fluid?
It has increased concentrations of K, phosphate, Mg, sulfur, and decreased concentrations of Na, Cl, and HCO3 ions
