settings are often most liquids, and the
solvent is nearly always _____
WATER
Solvents other than Water
ETHANOL, CHLOROFOAM, TOLUENE
a procedure to
remove waste products and
excess fluid from the blood
when the kidneys stop
working properly
a treatment typically
given to patients who have
kidney failure, or end-stage
renal disease (ESRD),
Injuries and conditions like
high blood pressure, diabetes

Dialysis
How does Dialysis work?
w o r k s b y u sin g a dialy sis m a c hin e, in w hic h it r e m o v e s blo o d f r o m a n e e dle in y o u r a r m, cir c ula t e s t h e blo o d t h r o u g h t h e dialy z e r filt e r, w hic h m o v e s w a s t e in t o a dialy sis s olu tio n. T his cle a n sin g liq uid c o n t ain s w a t e r, salt and other additives, then it filters blood to your body through a different needle in your arm. It also monitors your blood pressure to adjust how fast blood flows in and out of your body
procedure where a dialysis
machine and a special filter called an artificial kidney,
or a dialyzer, are used to clean your blood.
Hemodialysis
a mixture between
two substances, one of which is
finely divided and dispersed in the
other. Common suspensions
include sand in water, dust in air,
and droplets of oil in air
suspension
type of mixture
intermediate between a
homogeneous mixture (also called
a solution) and a heterogeneous
mixture with properties also
intermediate between the two.
colloid
liquid materials
generally with a white to milky white
color, consisting of water and
synthetic resin particles that are
uniformly dispersed in the water
Emulsions
Suspension Examples
Muddy water
*Milk of magnesia
*Sand particles suspended in water
Colloids Examples
Aerosols: Solid or liquid mixed with gas;
Example: fog (liquid in gas)
*Sols: Solid mixed with liquid; Example: Paint
*Emulsion: Liquid with liquid; Example: oil and water
*Gel: liquid in solid; Example: Fruit jelly
What happens when a red blood cell is placed in hypotonic solution?
When the cell presents with the same concentration on the inside and

causing it to ___.
Which of the following is true?
Movement of water molecules from a solution with
a high concentration of water molecules to a
solution with a lower concentration of water
molecules, through a cell’s semi-permeable
membrane.
Osmosis
