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.

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.
