PRACTICAL WORK


Examine a dissectible model of the human abdomen (Fig. 75), noting the
form, location, and connection of the different organs. Find the
connection of the esophagus with the stomach, of the stomach with the
small intestine, and of the small intestine with the large intestine.
Sketch a general outline of the cavity, and locate in this outline its
chief organs.

Where it is desirable to learn something of the actual structure of the
digestive organs, the dissection of the abdomen of some small animal is
necessary. On account of unpleasant features likely to be associated with
such a dissection, however, this work is not recommended for immature
pupils.
