- 10. What are the 5 most important electrolytes?
- Na, Cl, K, Mg, sulfate, phosphate, and HCO3.
- 7. Where is the thirst center located?
- hypothalamus
- 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
