~12. The Intestine~(in-tes'-tine).--At the lower end of the stomach
the digestive canal becomes narrow again. This narrow portion, called
the _intestine_, is about twenty-five feet long in a grown person. The
last few feet of the intestine is larger than the rest, and is called
the _colon_. This long tube is coiled up and snugly packed away in the
cavity of the abdomen. In the membrane lining the intestines are to be
found little glands, which make a fluid called _intestinal juice_.

~13. The Liver.~--Close up under the ribs, on the right side of the
body, is a large chocolate-colored organ, called the _liver_. The liver
is about half as large as the head, and is shaped so as to fit snugly
into its corner of the abdomen. The chief business of the liver is to
make a fluid called _bile_, which is very necessary for the digestion of
our food.

~14.~ The bile is a bitter fluid of a golden-brown color. It is carried
to the intestine by means of a little tube or duct, which enters the
small intestine a few inches below the stomach. When the bile is made
faster than it is needed for immediate use, it is stored up in a little
pear-shaped sac called the _gall-bladder_, which hangs from the under
side of the liver.

~15.~ The liver is a very wonderful organ, and does many useful things
besides making bile. It aids in various ways in digesting the food, and
helps to keep the blood pure by removing from it harmful substances
which are formed within the body.

~16. The Pancreas~(pan'-cre-as).--The _pancreas_ is another large and
very important gland which is found close to the stomach, lying just
behind it in the abdominal cavity. The pancreas forms a fluid called the
_pancreatic juice_, which enters the small intestine at nearly the same
place as the bile.

~17. The Spleen.~--Close to the pancreas, at the left side of the body,
is a dark, roundish organ about the size of the fist, called the
_spleen_. It is not known that the spleen has much to do in the work of
digestion, but it is so closely connected with the digestive organs that
we need to know about it.

~18.~ Please note that there are five important organs of digestion. The
mouth, the stomach, the intestines, the pancreas, and the liver.

~19.~ Also observe that there are five digestive fluids, saliva,
gastric juice, bile, pancreatic juice, and intestinal juice.
