GENERAL CONCLUSIONS.

other products for which the latter may serve as vehicle, bilirubin, 

 earthy salts, etc., to the vesicular vacuole of the cell and eliminated 

 by the canaliculus that opens into the bile-capillaries. 



10. The liliary acids, blood-pigments, iron, and other bodies 

 or any of their components, that may prove useful to the organism 

 are, entirely or in part, reabsorbed by the intestinal venules and 

 returned to the portal circulation. 



11. The sugars converted from intestinal foodstuffs in the 

 intestines are brought to the hepatic lobule with the portal blood, 

 and penetrate the canaliculi with the latter and with the oxidizing 

 substance. During the bile-forming reaction the sugars are de- 

 hydrated, and, probably with the assistance of the cellular proto- 

 plasm, converted into glycogen. 



12. The liver glycogen is converted into dextrose by an amy- 

 lolytic ferment supplied by the pancreas as an internal secretion, 

 which enters the portal circulation by the splenic vein. 



18. Dextrose is distributed to the organs in which it is used 

 as a source of energy by the blood, and only becomes vulnerable to 

 oxidation when combined with products of metabolism furnished 

 by those organs.
