CIRCULATION OF THE BLOOD-ACTION OF THE HEART. 



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

 the heart Impulse of the heart Succession of the movements of the heart Force of the heart- 

 Action of the valves Sounds of the heart Causes of the sounds of the heart Frequency of the 

 heart's action Influence of age and sex Influence of. digestion Influence of posture and muscu- 

 lar exertion Influence of exercise etc. Influence of temperature Influence of respiration on the 

 action of the heart -Cause of the rhythmical contractions of the heart Accelerator nerves Direct 

 inhibition of the heart Reflex inhibition of the heart Summary of certain causes of arrest of the 

 action of the heart 29 



CHAPTER III. 



CIRCULATION OF THE BLOOD IN THE VESSELS. 



Physiological anatomy of the arteries Course of blood in the arteries Locomotion of the arteries and 

 production of the pulse Pressure of blood in the arteries Pressure in different parts of the arterial 

 system Depressor nerve Influence of respiration on the arterial pressure Rapidity of the current 

 of blood in the arteries Rapidity in different parts of the arterial system Circulation of the blood 

 , in the capillaries Physiological anatomy of the capillaries Pressure of blood in the capillaries- 

 Relations of the capillary circulation to respiration Causes of the capillary circulation Influence 

 of temperature on the capillary circulation Influence of direct irritation on the capillary circulation 

 Circulation of the blood in the veins Physiological anatomy of the veins Course of the blood in 

 the veins Pressure of blood in the veins Rapidity of the venous circulation Causes of the venous 

 circulation Air in the veins Uses of the valves Conditions which impede the venous circulation 

 Regurgitant venous pulse Circulation in the cranial cavity Circulation in erectile tissues- 

 Derivative circulation Pulmonary circulation Circulation in the walls of the heart Passage of 

 the blood-corpuscles through the walls of the vessels (diapedesis) Rapidity of the circulation 

 Phenomena in the circulatory system after death 60
