QUESTIONS MISSED/GUESSED ON
MASTERING A & P EXAM.
HYPERTONIC - CORRECT ANSWER HYPER=MORE
Having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
(Solute concentration of the ECF is HIGHER than the solute concentration of the cytosol) Water moves
by osmosis toward the MORE CONCENTRATED solution so cell in HYPERTONIC solution loses water
because it leaves the cell and enters the ECF.
CELL LOSES WATER
RBC in hypertonic solution shrinks/shrivels (CRENATES) and possibly dies.
IF YOU PUT SOMETHING IN A SOLUTION THAT IS MORE CONCENTRATED THAN ITSELF YOU ARE PUTTIN
GIT IN A HYPERTONIC SOLUTION.
HYPOTONIC - CORRECT ANSWER HYPO=LESS
(In diagram on practice test with big round cell, the solute concentration of the extracellular solution
(ECF) is LESS concentrated than that of the cytosol (in the cell)
Because the cytosol is MORE concentrated, water MOVES INTO the cytosol by osmosis which causes the
cell to swell and possibly burst (LYSE)
IF YOU PUT SOMETHING INTO A SOLUTION THAT IS LESS CONCENTRATED THAN ITSELF YOU ARE
PUTTING IT IN A HYPOTONIC SOLUTION.
ISOTONIC - CORRECT ANSWER Same concentration of solute on both sides.
TONICITY - CORRECT ANSWER way to compare the osmotic pressure gradient between two
solutions/the relative solute concentration)
NOT PART OF THE ENDOMEMBRANE SYSTEM - CORRECT ANSWER PEROXISOME (Lysosome, Golgi, and
ER are all part of it.)
Both cilia and flagella are constructed of a ring of nine pairs of microtubules surrounding two central
microtubules. - CORRECT ANSWER TRUE
