Flashcards in Fluid, Electrolyte and Balance Deck (155)
Between an adult male, female, elder, and baby which has the higher body water content?
the baby due to low body fat therefore low bone mass
Why do males have 10 percent more body water content that females?
Males have more skeletal muscle than women who have higher body fat
What are the 2 main fluid compartments?
Intracellular fluid and extracellular fluid
What are the 2 subparts of the extracellular fluid? Percentages?
What is the fluid in the blood called?
Which of the compartments consist of 2/3 total fluid content?
What is the fluid between cells called?
Which of the compartments consist of 1/3 total fluid content?
What is the percentage of the ICF in the body?
What is the percentage of ECF in the body?
What is the percentage of the total body weight of ECF and ICF?
do not dissociate in water; no charged particles are created
dissociate into ions in water; ions conduct electrical current
What are some examples of electrolytes?
acids, bases, salts, and some proteins
What are some examples of nonelectrolytes?
glucose and most organic molecules
What is the major cation in the ECF?
What is the major anion in the ECF?
What is the major cation in the ICF?
What is the major anion in the ICF?
Where are the electrolyte concentrations similar except for higher protein content of plasma?
Where are there more proteins than in plasma?
Where do exchanges between plasma and IF occur?
Across capillary walls
Where do exchanges between IF and ICF occur?
Across plasma membranes
What must occur for the body to remain stable?
its inout through ingestion or metabolic production = its output through excretion or metabolic consumption
Which 2 factors are regulated to maintain fluid balance?
1. ECF osmolality
2. ECF volume
How is ECF osmolality regulated?
must be regulated to prevent swelling or shrinking of cells
What is ECF osmolality involved in maintaining?
How is ECF volume regulated?
must be regulated to help maintain BP
What is ECF volume involved in maintaining?
maintaining sodium balance
