THE MECHANISM OF THE CIBCULATION OF 

 THE BLOOD. 



BY LEONARD HILL. 



ACTION OF HEART Form of Heart Valves and Papillary Muscles Pressure in 

 Cavities Heart Sounds Heart Impulse Work of Heart Diastolic Filling of 

 Heart Systolic Output Action of Nerves Cardiac Centres and Reflexes 

 Depressor Nerve H^MODYNAMICS Torricelli's Law Poiseuille's Law 

 General Principles of Circulation Pressure in Arteries Velocity of Flow 

 Circulation Time Effect of Change of Posture on Circulation The Pulse 

 THE CAPILLARY CIRCULATION Microscopical Examination Rate of Flow 

 Capillary Pressure BLOOD FLOW IN THE VEINS Pressure in Veins Effect of 

 Muscular Movements Rate of Flow INFLUENCE OF RESPIRATION ON CIRCULA- 

 TION VASOMOTOR MECHANISM Historical Methods Action of Vaso-dilators 

 Local Tone Traube-Hering Curves Vasomotors of Veins CIRCULATION IN 

 SPECIAL PARTS Cerebral Circulation Pulmonary Circulation Blood Flow in 

 Limbs Renal Circulation Mesenteric Circulation Hepatic Circulation

THE CONTKACTION OF CAEDIAC MUSCLE. 

 BY W. H. GASKELL. 



The Meaning of the Heart-Beat The Sequence of the Contractions of the different 

 Parts of the Heart The Causation of the Beat of the Heart and of the Sequence 

 of the Contractions of the Separate Cavities is the same in Warm-blooded as 

 in Cold-blooded Animals The Peculiarities of the Cardiac Muscle by which 

 the Rhythm and Sequence are to be explained On Fibrillar Contraction 

 On the Tonicity of the Cardiac Muscle The Meaning of the Ganglion Cells 

 in the Heart, and their Relation to the Cardiac Nerves The Nature of the 

 Action of the Cardiac Nerves : (1) The Inhibitory Nerves, (2) the Augmentor 

 Nerves, (3) the After-Action of the Inhibitory and Augmentor Nerves The 

 Action of Certain Poisons On the Nutrition of the Heart . . page 169
