water makes up ____% in men - ANSWER-60%
water makes up ____% in women - ANSWER-50%
made up of 2/3 (40%) of water - ANSWER-intracellular
made up of 1/3 (20%) of water - ANSWER-extracellular
what two things make up extracellular fluid? - ANSWER-Intravascular and interstitial
what % of intravascular is in the extracellular? - ANSWER-25%
what % of interstitial is in the extracellular? - ANSWER-75%
who has more water, men or women? - ANSWER-men
who has more water, elderly or pediatric? - ANSWER-pediatric
why does total body water decrease as we age? - ANSWER-decreased free fat and
muscle mass
renal decline
diminished thirst perception
Starling forces - ANSWER-forces affecting movement of fluid between cells and spaces
net filtration - ANSWER-forces favoring filtration minus forces opposing filtration
Osmolarity - ANSWER-concentration of osmotically active particles in a solution
isosmotic - ANSWER-solutions with the same concentrations of solute particles
(osmolarity)
hyposomotic - ANSWER-solution with lower osmotic pressure. lower outside
hyperosmotic - ANSWER-solution with higher osmolarity. higher inside.
isotonic - ANSWER-two solutions with the same osmotic pressure
Hypotonic - ANSWER-when comparing two solutions, the solution with the lesser
concentration of solutes within the cell
, Hypertonic - ANSWER-when comparing two solutions, the solution with the greater
concentration of solutes within the cell
Forces favoring filtration - ANSWER-Capillary hydrostatic pressure (blood pressure) and
interstitial oncotic pressure (water-pulling)
Forces favoring reabsorption - ANSWER-Plasma (capillary) oncotic pressure (water-
pulling)
Interstitial hydrostatic pressure
edema - ANSWER-accumulation of fluid within the interstitial spaces
causes of edema - ANSWER-increased capillary hydrostatic pressure (increased BP),
decrease of plasma oncotic pressure,
obstruction of lymphatic circulation,
increased capillary permeability
What is ascites? - ANSWER-accumulation of fluid in the peritoneal cavity
example of increased capillary hydrostatic pressure - ANSWER-venous obstruction, salt
and water retention, heart failure, renal failure
what does increased capillary hydrostatic pressure cause? - ANSWER-forces fluid into
tissues
causes of decreased capillary (plasma) oncotic pressure - 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? - ANSWER-fluid movement into the tissues
decreased transport of capillary filtered protein ( thus increasing tissue oncotic
pressure)
what are examples of increased capillary permeability? - ANSWER-burns and
inflammation
What do ACE inhibitors do? - ANSWER-decrease sodium and volume= lowers BP by
inhiniting angiotensin II which narrown vessels to raise Bp
Natriuretic peptides - ANSWER-removes sodium through kidneys to decrease fluid
volume.
decreases BP, sodium, and fluid
