VPHY 3100 Test 1 - Chapter 6 questions with
complete solutions already passed
1. What is a solvent? In the case of physiology, it is water
2. What is the solute? Anything dissolved in water
3. What percentage Intracellular - 67%
of each cellular
Extracellular - 33% (majority of this is interstitial fluid and the rest is
compo- nent is
vascular fluid)
water?
Everything that lies outside the cell
4. What is the
extracel- lular
environment? Gel-like hydrated madeira that is rich of polymers and is viscous even
5. Describe the though it is also aqueous - there are glycoproteins, proteoglycans,
Extra- cellular collagen, elastin
matrix and what
it is composed of
6. What molecules/sub- gases, ethanol, urea, small uncharged polar molecules, H2O (kind
of, it
stances can cross accomplishes difusion via osmosis)
the cellular
mem- brane via
simple dif- fusion?
7. What molecules/sub- Large uncharged polar molecules, Ions, charged polar
molecules
stances require
car- rier
mediated trans-
port to cross the
cel- lular
membrane?
