bio 669 quiz 1 Questions &
Answers(GRADED A+)
water makes up ____% in men - ANSWER60%



water makes up ____% in women - ANSWER50%



made up of 2/3 (40%) of water - ANSWERintracellular



made up of 1/3 (20%) of water - ANSWERextracellular



what two things make up extracellular fluid? - ANSWERIntravascular and interstitial



what % of intravascular is in the extracellular? - ANSWER25%



what % of interstitial is in the extracellular? - ANSWER75%



Starling forces - ANSWERforces affecting movement of fluid between cells and spaces



net filtration - ANSWERforces favoring filtration minus forces opposing filtration



Osmolarity - ANSWERconcentration of osmotically active particles in a solution



isosmotic - ANSWERsolutions with the same concentrations of solute particles (osmolarity)



hyposomotic - ANSWERsolution with lower osmotic pressure. lower outside



hyperosmotic - ANSWERsolution with higher osmolarity. higher inside.

,isotonic - ANSWERtwo solutions with the same osmotic pressure



Hypotonic - ANSWERwhen comparing two solutions, the solution with the lesser concentration of
solutes within the cell



Hypertonic - ANSWERwhen comparing two solutions, the solution with the greater concentration of
solutes within the cell



Forces favoring filtration - ANSWERCapillary hydrostatic pressure (blood pressure) and interstitial
oncotic pressure (water-pulling)



Forces favoring reabsorption - ANSWERPlasma (capillary) oncotic pressure (water-pulling)

Interstitial hydrostatic pressure



who has more water, men or women? - ANSWERmen



who has more water, elderly or pediatric? - ANSWERpediatric



why does total body water decrease as we age? - ANSWERdecreased free fat and muscle mass

renal decline

diminished thirst perception



edema - ANSWERaccumulation of fluid within the interstitial spaces



causes of edema - ANSWERincreased capillary hydrostatic pressure (increased BP),

decrease of plasma oncotic pressure,

obstruction of lymphatic circulation,

increased capillary permeability



What is ascites? - ANSWERaccumulation of fluid in the peritoneal cavity

, example of increased capillary hydrostatic pressure - ANSWERvenous obstruction, salt and water
retention, heart failure, renal failure



what does increased capillary hydrostatic pressure cause? - ANSWERforces fluid into tissues



causes of decreased capillary (plasma) oncotic pressure - ANSWERdecreased 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)

papilledema - ANSWERswelling and inflammation of the optic nerve at the point of entrance into the
eye through the optic disk



What causes papilledema? - ANSWERoften caused by increase in intracranial pressure



what is the primary extracellular fluid cation (positive charged ion)? - ANSWERSodium



movement of sodium in cell does what to hydrogen? - ANSWERpushes hydrogen out.



increase in sodium does what to fluid volume? - ANSWERincreases fluid volume



what is the primary extracellular anion? - ANSWERChloride



what if sodium goes in the cell what does the chloride do? - ANSWERfollows it in.



what is the amount of sodium in the extracellular fluid? - ANSWER142



what is the amount of sodium in the intracellular fluid? - ANSWER12



what does lymph obstruction cause? - ANSWERfluid movement into the tissues

decreased transport of capillary filtered protein ( thus increasing tissue oncotic pressure)



what are examples of increased capillary permeability? - ANSWERburns and inflammation
