CIRCULATION OF THE BLOOD. 



Discovery of the circulation Physiological anatomy of the heart Valves of the 

 heart Movements of the heart Impulse of the heart Succession of move- 

 ments of the heart Force of the heart Action of the valves Sounds of the 

 heart Cause of the sounds of the heart, .... Page 170 



CHAPTER V. 



FEEQUENOY OF THE HEABl's ACTION. 



Frequency of the heart's action Influence of age Influence of digestion Influ- 

 ence of posture and muscular exertion Influence of exercise Influence of 

 temperature Influence of respiration on the action of the heart Cause of 

 the rhythmical contractions of the heart Influence of the nervous system on 

 the heart Division of the pneumogastrics Galvanization of the pneumogas- 

 trics Causes of the arrest of action of the heart Blows upon the epigas- 

 trium, 211 



CHAPTER VI. 



CIBCULATION OF THE BLOOD IN THE AETERIES. 



Physiological anatomy of the arteries Course of blood in the arteries Elasticity 

 of the arteries Contractility of the arteries Locomotion of the arteries and 

 production of the pulse Form of the pulse Sphygmograph Pressure of 

 blood in the arteries Hemodynamometer Cardionieter Differential cardio- 

 meter Pressure in different parts of the arterial system Influence of respi 

 ration on the arterial pressure Effects of hemorrhage Rapidity of the cur- 

 rent of blood in the arteries Instruments for measuring the rapidity of the 

 arterial circulation Variations in rapidity with the action of the heart Ra- 

 pidity hi different parts of the arterial system Arterial murmurs, . . 240 



CHAPTER VII. 



CIRCULATION OF THE BLOOD IN THE CAPILLARIES. 



Distinction between. capillaries and the smallest arteries and veins Physiological 

 anatomy of the capillaries Peculiarities of distribution Capacity of the 

 capillary system Course of blood in the capillaries Phenomena of the 

 capillary circulation Rapidity of the capillary circulation Relations of the 

 capillary circulation to respiration Causes of the capillary circulation In- 

 fluence of temperature on the capillary circulation Influence of direct irrita- 

 tion on the capillary circulation, 278
