THE :\IECHANISMS OF DIGESTION 307 The dextrins themselves however are in most cases more complex bodies than is here represented, belonging, like the parent molecule, to the class of bodies known as colloids. The Mechanism of Salivary Secretion The digestive juices are formed by the agency of glands. These are recesses or branching tubules lined with a con- tinuation of the general alimentary epithelium. This secre- tory epithelium is separated by a basement membrane from the surrounding connective tissue, in which ramify blood- vessels, lymphatics, and nerves. The secretory cells are bathed by the lymph that exudes from the capillaries ; and from this lymph they select the substances necessary for their nourishment, and form therefrom the special ingredients Fici.
