-
ANS
solutions
with
the
same
concentrations
of
solute
particles
(osmolarity)

ANS
solution
with
lower
osmotic
pressure.
lower
outside
hyperosmotic
-
ANS
solution
with
higher
osmolarity.
higher
inside.
isotonic
-
ANS
two
solutions
with
the
same
osmotic
pressure
Hypotonic
-
ANS
when
comparing
two
solutions,
the
solution
with
the
lesser
concentration
of
solutes
within
the
cell Hypertonic
-
ANS
when
comparing
two
solutions,
the
solution
with
the
greater
concentration
of
solutes
within
the
cell
Forces
favoring
filtration
-
ANS
Capillary
hydrostatic
pressure
(blood
pressure)
and
interstitial
oncotic
pressure
(water-pulling)
Forces
favoring
reabsorption
-
ANS
Plasma
(capillary)
oncotic
pressure
(water-pulling)
Interstitial
hydrostatic
pressure
edema
-
ANS
accumulation
of
fluid
within
the
interstitial
spaces
causes
of
edema
-
ANS
increased
capillary
hydrostatic
pressure
(increased
BP),
decrease
of
plasma
oncotic
pressure,
obstruction
of
lymphatic
circulation,
increased
capillary
permeability
What
is
ascites?
-
ANS
accumulation
of
fluid
in
the
peritoneal
cavity
example
of
increased
capillary
hydrostatic
pressure
-
ANS
venous
obstruction,
salt
and
water
retention,
heart
failure,
renal
failure
what
does
increased
capillary
hydrostatic
pressure
cause?
-
ANS
forces
fluid
into
tissues
causes
of
decreased
capillary
(plasma)
oncotic
pressure
-
ANS
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?
-
ANS
fluid
movement
into
the
tissues
decreased
transport
of
capillary
filtered
protein
(
thus
increasing
tissue
oncotic
pressure)
what
are
examples
of
increased
capillary
permeability?
-
ANS
burns
and
inflammation
what
does
increased
capillary
permeability
do?
-
ANS
proteins
escape=
loss
of
plasma
proteins
to
interstitial
space
(thus
increasing
tissue
oncotic
pressure
and
decreased
capillary
oncotic
pressure)
papilledema
-
ANS
swelling
and
inflammation
of
the
optic
nerve
at
the
point
of
entrance
into
the
eye
through
the
optic
disk
What
causes
papilledema?
-
ANS
often
caused
by
increase
in
intracranial
pressure
what
is
the
primary
extracellular
fluid
cation
(positive
charged
ion)?
-
ANS
Sodium
