Bio 669 Quiz 1 with Accurate Solutions
water makes up ____% in men - correct Answer-60%
water makes up ____% in women - correct Answer-50%
made up of 2/3 (40%) of water - correct Answer-intracellular
made up of 1/3 (20%) of water - correct Answer-extracellular
what two things make up extracellular fluid? - correct Answer-Intravascular and
interstitial
what % of intravascular is in the extracellular? - correct Answer-25%
what % of interstitial is in the extracellular? - correct Answer-75%
who has more water, men or women? - correct Answer-men
who has more water, elderly or pediatric? - correct Answer-pediatric
why does total body water decrease as we age? - correct Answer-decreased free fat
and muscle mass
renal decline
diminished thirst perception
Starling forces - correct Answer-forces affecting movement of fluid between cells and
spaces
net filtration - correct Answer-forces favoring filtration minus forces opposing filtration
Osmolarity - correct Answer-concentration of osmotically active particles in a solution
isosmotic - correct Answer-solutions with the same concentrations of solute particles
(osmolarity)
hyposomotic - correct Answer-solution with lower osmotic pressure. lower outside
hyperosmotic - correct Answer-solution with higher osmolarity. higher inside.
isotonic - correct Answer-two solutions with the same osmotic pressure
, Hypotonic - correct Answer-when comparing two solutions, the solution with the lesser
concentration of solutes within the cell
Hypertonic - correct Answer-when comparing two solutions, the solution with the greater
concentration of solutes within the cell
Forces favoring filtration - correct Answer-Capillary hydrostatic pressure (blood
pressure) and interstitial oncotic pressure (water-pulling)
Forces favoring reabsorption - correct Answer-Plasma (capillary) oncotic pressure
(water-pulling)
Interstitial hydrostatic pressure
edema - correct Answer-accumulation of fluid within the interstitial spaces
causes of edema - correct Answer-increased capillary hydrostatic pressure (increased
BP),
decrease of plasma oncotic pressure,
obstruction of lymphatic circulation,
increased capillary permeability
What is ascites? - correct Answer-accumulation of fluid in the peritoneal cavity
example of increased capillary hydrostatic pressure - correct Answer-venous
obstruction, salt and water retention, heart failure, renal failure
what does increased capillary hydrostatic pressure cause? - correct Answer-forces fluid
into tissues
causes of decreased capillary (plasma) oncotic pressure - correct Answer-decreased
plasma albumin
-decreased synthesis of plasma proteins (cirrhosis, malnutrition)
-increased loss of plasma proteins (nephrotic syndrome)
increased Na+ and H2O retention (dilution of plasma proteins)
what does lymph obstruction cause? - correct Answer-fluid movement into the tissues
decreased transport of capillary filtered protein ( thus increasing tissue oncotic
pressure)
what are examples of increased capillary permeability? - correct Answer-burns and
inflammation
what does increased capillary permeability do? - correct Answer-proteins escape= loss
of plasma proteins to interstitial space (thus increasing tissue oncotic pressure and
decreased capillary oncotic pressure)
