360 DETAILED SYNTHESIS. 



NOT TET AGREED how the bile-ducts commence, nor how they obtain the 

 bile from the cells in which it is secreted. 



1098. THE LIVER is FURNISHED with only a smafi 

 artery, supposed to supply the nutrient blood ; but that 

 from which the bile is secreted is supplied through the 

 branches of a vein (portal), that is composed of five, one 

 from the stomach, spleen, pancreas, and two from the 

 second stomach : these unite to form one, and through it 

 pour their contents into the liver. 



1099. Inf. It is obvious that THE BLOOD FROM THE FIVE ORGANS 

 MENTIONED does not FLOW back directly to the heart, but ere that organ 

 is reached it is operated upon By the liver ; a peculiarity of the circulation 

 worthy of notice and being remembered. "^Q 



1100. IT is ALSO ASCERTAINED that some of the cells 

 of the liver secrete from the Blood, and yield back to it, 

 a sweet substance, called liver-sugar ; for the Blood that 

 flows from the liver is sweeter than that which flows 

 into it. 



1101. Inf. THE LIVER MAY BE CALLED A DOUBLE GLAND, having a 

 double office, to secrete bile, and remove it from the Blood, and to trans- 

 form some of its elements into sugar. 



1102. Remark. BY WHAT PROCESS, change, or from what source, 

 THE SUGAR is PRODUCED IN THE LIVER, is not yet understood. It may be 

 that the secretion of the bile produces such a condition in the Blood 

 that sugar is formed as a necessary result, and without any further 

 secretion. 



1103. THE LIVER, BY PRODUCING SUGAR, BECOMES 

 an assistant heat-producing organ. 



1104. Remark. Hence, if it is deranged, and the other organs can 

 deposit fat, it may be expected they will do so, that the heat produced 

 may be preserved thereby. Accordingly it not unfrequently happens 

 that derangement of the liver, as effected by the use of ale, lager beer, 

 etc., will be followed by deposits of fat. On the other hand, if the 

 liver is deranged, and .the other organs cannot deposit fat, as is gen- 

 erally the case when distilled alcoholics are used, leanness and pallor 

 follow.
