____ is the most abundant body compound
water
body fluids:
references to "average" body water volume based on healthy, nonobese, (154 lb.) male
water is ___ % of body weight in males
60
water is ___ % of body weight in females
50
volume averages ___ L in 154 lb. male
40
variation in total body water is related to:
total body weight of individual
variation in total body water is related to:
fat content of body - the more fat, the less water
variation in total body water is related to:
sex - female body about 10% less than male body
female body is about ___ % less than male
10
the more ____, the less ____
fat, water
_____ _____ is low in water content
adipose tissue
in newborn infants, water may account for ____ % of total body weight
80
in elderly, water per pound of weight decreases
muscle tissue, 65% water, is replaced by fat, which is 20% water
muscle tissue is:
65% water
fat is:
20% water
there are ___ major fluid compartments
2
two major fluid compartments:
extracellular and intracellular
extracellular fluid:
ECF
extracellular fluid is called the _____ ______ of the body
internal environment
extracellular fluid _____ cells and _____ substances to and from them
surrounds, transports
intracellular fluid:
ICF
intracellular fluid:
larger fluid compartment
intracellular fluid is located ____ cells
inside
intracellular fluid serves as a:
solvent to facilitate intracellular chemical reactions
fluid output, mainly ____ ____, adjusts to fluid intake
urine volume
ADH:
antidiuretic hormone
ADH from ____ pituitary gland acts to increase kidney tubule reabsorption of _____ and water from tubular urine into blood
posterior, sodium
concentration of _____ (primarily sodium) in extracellular fluid influences volume of ______ fluid
electrolytes, extracellular
increase in _____ in the blood tends to _____ volume of blood
sodium, increase
increase in sodium in the blood tends to increase volume of blood by:
increasing movement of water out of ICF and into the ECF
increase in sodium in the blood tends to increase volume of blood by:
increasing ADH secretion, which decreases urine volume, and this, in turn, increases ECF volume
nonelectrolytes are _____ substances that do not break up or _____ when placed in water solution:
organic, dissociate
example of nonelectrolyte:
glucose
electrolytes are _____ that break up or _____ in water solution into separate particles called _____
compounds, dissociate, ions
example of electrolyte:
ordinary table salt or sodium chloride
ions are the _____ particles of an electrolyte that carry an ____ charge
dissociated, electrical
positively charged ions:
potassium (K+) and sodium (Na+)
negatively charged ions:
chloride (Cl-) and bicarbonate (HCO3-)
ions:
electrolyte composition of blood plasma
____ is the most abundant and important positively charged ion of plasma
sodium
normal plasma level:
135-145 mEq/L
average daily intake (diet):
100 mEq
chief method of regulation:
kidney
_____ increases Na reabsorption from kidney tubules
aldosterone
sodium:
containing internal secretions
_____ _____ _____ pushes water out of blood into interstitial fluid
capillary blood pressure
IF:
interstitial fluid
____ ____ ____ pulls water into blood from interstitial fluid
blood protein concentration
capillary blood pressure and blood protein concentration:
regulate plasma and interstitial fluid volume under usual conditions
Total volume of body fluids less than normal
dehydration
in dehydration _____ _____ ____ shrinks first; if treatment is not given, intracellular fluid volume and ____ ____ decrease
interstitial fluid volume, plasma volume
______ occurs when ____ ____ exceeds intake for an extended period
dehydration, fluid output
total volume of body fluids greater than normal
overhydration
_____ occurs when ____ ____ exceeds output
overhydration, fluid intake
factors that cause overhydration:
giving excessive amounts of intravenous fluids
factors that cause overhydration:
giving intravenous fluids too rapidly
