out from the walls of the stomach.
The main duty of this gastric juice is
to change the aIbuminoids into form
in which they can be absorbed and
used by the animal.
Cattle ard sheep have a very large
stomach, which is divided into four
parts. Animals Of this kind are called
ruminants. When the food is swallow
ed it passes into the first stomach,
which serves the purpose Of store
house. Here the action of the saliva
continues, and the water which the
animal drinks softens the food to a
considerable extent. After time the
food passes into the second stomach,
which forces it back to the mouth,
little at a time. Here it is chewed
thoroughly. You have often seen
COWS lying in the shade "chewing
their cud." This cud is the food that
has been sent up to the mouth by the
second stomach.
After being chewed the food is
swallowed again. This time it passes
directly through the first stomach to
the third. Here it becomes still fur
Their softened, finally passing into the
fourth or true stomach. The function
Of the first three compartments is
simply to prepare the food to be acted
upon by the true stomach.
After leaving the stomach the par
TALLY digested food passes into the
small intestines. Here it is acted
upon by three fuids-the bile, pan
create juice and intestinal juice. The
chief use of the bile is to digest the
fats, making them into sort of a
soapy fluid, in which form they are
ready to be absorbed into the blood.
Both the pancreatic and intestinal
juices act upon the remaining starch,
completing the change into sugar. The
pancreatic juice also completes the di-
gestion of the albuminoids, in which
work the intestinal juice may also
take small part. Another work OF
the pancreatic juice is to assist IN
decomposing the fats. The Intestinal
juice breaks cane sugar up into SIM
pier sugars, such as glucose
After the food has been digested the
disable portions are ready to be alb
sorbed into the blood. Digestion has
changed the fats, proteins and starches
into a form in which they are soluble
In this fluid state they pass through
the walls of the stomach and intestines
and are emptied into the blood.
The blood is taken to all parts Of the
body by the arteries, which subdivfde
to form tiny capillaries. These are sc
small and close together that a pir
prick on the skin anywhere will pierce
some of them. There are two main
parts to the blood-the fluid Of plasms
and the red corpuscles-which give II
its color.
| Each part Of the body selects from
the blood the food materials which II
needs. Thus the bones will take ash
while the muscles will take protein
to build up their wornout parts. Th'
waste, broken down parts are burned
together with as much fats and sug
ars as are needed, to furnish heat anC
energy. All through the body there
are thousands of little fires. To keeI
these fires going oxygen is used, ant
carbon dioxide is given off in the SAM
way that a fire in stove takes IL
oxygen through the lower draft ant
sends carbon dioxide up the chimney.
In the body the corpuscles supply
the oxygen and carry away the car
bon dioxide. The other waste ma
terials, or ashes, are gathered up b!
a system Of vessels called lymphatics
which empty into the veins. Thes'
veins carry the blood back to tn
heart. The change Of the contents o
the corpuscles from oxygen to car
bon dioxide changes the color Of tn
blood from a bright red to mucl
darker shade.
