FUNCTIONS OF THE LIVER. 



Physiological anatomy of the liver Distribution of the portal vein, the hepatic artery, and the hepatic duct 

 Origin and course of the hepatic veins Structure of a lobule of the liver Arrangement of the bile-ducts in 

 the lobules Anatomy of the excretory biliary passages Nerves and lymphatics of the liver Mechanism of 

 the secretion and discharge of bile Quantity of bile Variations in the flow of the bile Discharge of bile from 

 the gall-bladder General properties of the bile Composition of the bile Origin of the biliary salts Choles- 

 terine Biliverdine Tests for bile Excretory function of the liver Origin of cholesterine Experiments show- 

 ing the passage of cholesterine into the blood as it circulates through the brain Elimination of cholesterine by 

 the liver Cholestersemia Production of sugar in the liver Evidences of a glycogenic function in the liver 

 Does the liver contain sugar during life? Mechanism of the production of sugar by the liver Glycogenic mat- 

 terVariations in the glycogenic function Production of sugar in foetal life Influence of digestion and of differ- 

 ent kinds of food upon glycogenesis Influence of the nervous system, etc., upon glycogenesis Artificial dia- 

 betesDestination of sugar Alleged production of fat by the liver Changes in the albuminoid and the corpus- 

 cular elements of the blood in their passage through the liver, 431

CHAPTEE XV. 



NUTRITION ANIMAL HEAT. 



Nature of the forces involved in nutrition Definition of vital properties Life, as represented in development and 

 nutrition Principles which pass through the organism Principles consumed in the organism Development of 

 power and endurance by exercise (training) Formation and deposition of fat Conditions under which fat exists 

 in the organism Physiological anatomy of adipose tissue Conditions which influence nutrition Products of 

 disassimilation Animal heat Limits of variation in the normal temperature in man Variations with external 

 temperature Variations in different parts of the body Variations at different periods of life Diurnal variations 

 Relations of animal heat to digestion Influence of defective nutrition and inanition Influence of exercise, 

 mental exertion, and the nervous system, upon the heat of the body Sources of animal heat Connection of the 

 production of heat with nutrition Seat of the production of animal heat Eelations of animal heat to the different 

 processes of nutrition Eelations of animal heat to respiration Exaggeration of the animal temperature in par- 

 ticular parts after division of the sympathetic nerve and in inflammation Intimate nature of the calorific pro- 

 cesses Equalization of the animal temperature, 4S(i

 untary muscular tissue Physiological anatomy of the voluntary muscles Fibrous and adipose tissue in the 

 voluntary muscles Connective tissue Blood-vessels and lymphatics of the muscular tissue Connection of
