What makes up approximately _______ percent of lean body weight in men?
|| || || || || || || || || || ||
women? - Correct answer ✔men = 60%.
|| || || || || ||
women = 50%. || ||
what fraction of water is in the intracellular space?
|| || || || || || || ||
extracellular space? - Correct answer ✔intracellular = two-thirds.
|| || || || || || ||
extracellular = one-third. || ||
Is the ICF or ECF subdivided into more categories?
|| || || || || || || ||
what are these? - Correct answer ✔ECF.
|| || || || || ||
Into intravascular and interstitial.
|| || ||
What percentage of the ECF is intravascular fluid?
|| || || || || || ||
,2
interstitial? - Correct answer ✔intravascular 25%. (4-5%)
|| || || || || ||
interstitial 75%. (15-16%) || ||
because most of the water is in the cells, volume changes are generally associated with:
|| || || || || || || || || || || || || ||
- Correct answer ✔change in serum osmolality and electrolyte concentrations.
|| || || || || || || || || ||
the distribution of body fluids follows this rule: - Correct answer ✔60-40-20 rule.
|| || || || || || || || || || || ||
60% of the total body weight is water.
|| || || || || || ||
40% of the body weight in cells in intracellular fluid (2/3 of total body weight).
|| || || || || || || || || || || || || ||
20% of the body weight is water outside of the cells. (1/3 of the total body weight).
|| || || || || || || || || || || || || || || ||
Other minute fluids within the ECF: - Correct answer ✔Lymph, synovial, intestinal, CSF,
|| || || || || || || || || || || || ||
sweat, urine, pleural, peritoneal,
|| || ||
pericardial, and intraocular fluids. || || ||
So a 100kg man (220lbs) has about ____ kg/liters of plasma. - Correct answer ✔5 kg
|| || || || || || || || || || || || || || ||
A 70 kg man has _____ TBW.
|| || || || || ||
___ kg ICF. || ||
_____kg ECF. ||
,2
________kg plasma - Correct answer ✔42 kg.
|| || || || || ||
28 kg.
||
14 kg.
||
3-3.5 kg.||
water is what percentage of pediatrics body weight is water? - Correct answer ✔75-80%.
|| || || || || || || || || || || || ||
therefore, children are susceptible to: - Correct answer ✔significant changes in body
|| || || || || || || || || || || ||
fluids.
Why is there a decrease percent of total body water with aging? - Correct answer ✔1.
|| || || || || || || || || || || || || || || ||
decreased free fat mass and decrease muscle mass.
|| || || || || || ||
2. renal decline.
|| ||
3. diminished thirst perception.
|| || ||
What are the most significant causes of dehydration in children? - Correct answer ✔1.
|| || || || || || || || || || || || || ||
urine loss.
||
2. fever which increases respirations and transpiration = sweating.
|| || || || || || || ||
, 2
Why are overweight individuals at a higher risk for dehydration than those at normal
|| || || || || || || || || || || || || ||
weights? - Correct answer ✔overweight individuals have lower amounts of total body
|| || || || || || || || || || || ||
weight due to adipose tissue being unable to contain water.
|| || || || || || || || ||
attractive forces that concerns ions ability to attract water. - Correct answer ✔osmotic
|| || || || || || || || || || || || ||
forces.
concerns how water primarily moves.
|| || || ||
Osmotic vs. Hydrostatic forces - Correct answer ✔Osmotic forces are attractive forces
|| || || || || || || || || || || ||
that pull water across the membrane.
|| || || || ||
Hydrostatic forces are mechanical forces that push water across the membrane. (from
|| || || || || || || || || || || ||
capillary to interstitial or vice versa).
|| || || || ||
What allows movement of water across the membrane? - Correct answer ✔aquaporins.
|| || || || || || || || || || || ||
allows water to move through diffusion.
|| || || || ||
How must ions travel across the plasma membrane? - Correct answer ✔through
|| || || || || || || || || || || ||
channels, carriers and pumps. They move in a more limited manner.
|| || || || || || || || || ||
Starling forces describes the forces that are: - Correct answer ✔affecting movement of
|| || || || || || || || || || || || ||
fluid between cells and spaces.
|| || || ||
The starling forces also describes the net filtration as: - Correct answer ✔the forces that
|| || || || || || || || || || || || || ||
are favoring filtration minus forces opposing filtration.
|| || || || || || ||
Primary sources of water intake include - Correct answer ✔1. drinking water orally.
