Questions and CORRECT Answers
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)
papilledema - CORRECT ANSWER✔✔- swelling and inflammation of the optic nerve at the
point of entrance into the eye through the optic disk
