body fluids

Question 1

what are the 2 component of ecf

Answer 1

interstitial&trancellular(15%) and intravascular(plasma volume)-5%

Question 2

the plasma or the intravascular fluid is composed of

Answer 2

92% water and 8% protein

Question 3

Answer 3

interstitial fluid

Question 4

Answer 4

trancellular fluid

Question 5

the trancellular fluid includes

Answer 5

intraocular fluid, cerebrospinal fluid, synovial fluid, bile, fluids of the digestive tract

Question 6

the principal component of cytosol

Answer 6

icf

Question 7

the actual space or volume in which a substance is dispersed

Answer 7

colume of distrubution (Vd)

Question 8

how to estimate the total blood volume

Answer 8

plasma volume/(1-hematocrit)

Question 9

the fraction of blood cpmposed of rbc, as determined by centrifuging blood is hematocrit tube until cells become tightly packed in the bottom of the tube

Answer 9

hematocrit/pcv

Question 10

how to manually determine the pcv

Answer 10

by measuring the height of the packed rbcs and total length of plasma and cellular components
%pcv=(x/y) x100

Question 11

the fluid that can be used to estimate the volume of different compartments using vd of a substance

Answer 11

total body fluid , icf, ecf, plasma, interstitial fluid volume, icf, blood

Question 12

t or f. the ionic compsition of plasma and interstitial fluid is the same

Answer 12

true

Question 13

the concentration of protein is higher in which compartment

Answer 13

plasma. bec the capillaries have a low permeability to the plasma proteins. so only small amounts leak to interstitial
