RESPIRATION. 



PAGE 



Nature of Respiration In Animals and Vegetables Organs of Respira- 

 tion Gills Lungs Movements of Respiration Their Frequency 

 Quantity of Air Used in Respiration Changes in the Air by Respiration 

 Absorption of Oxygen Exhalation of Carbonic Acid Exhalation of 

 Watery Vapor Of Organic Matter Vitiation of the Air by Respiration 

 Relations between the Oxygen Absorbed and the Carbonic Acid Given 

 Off Changes in the Blood by Respiration Color of Arterial and Venous 

 Blood Exchange of Gases in the Blood Destination of the Oxygen 

 Source of the Carbonic Acid Respiration by the Tissues . . 232-257

ANIMAL HEAT. 



Temperature of the Animal Body In Different Classes Internal Produc- 

 tion of Heat Quantity of Heat Produced in the Body Normal Varia- 

 tions of Temperature in the Body Mode of Production of Animal Heat 

 Relations of Heat-Production and Respiration Local Heat-Production 

 in the Organs and Tissues Cooling Action of the Lungs and Skin 

 Regulation of the Animal Temperature Effects of Lowering the Bodily 

 Temperature Effects of Elevating the Bodily Temperature Resistance 

 of the Body to External Cold Resistance of the Body to External 

 Heat 258-273 



CHAPTER VI. 



THE CIRCULATION. 



The Circulatory Apparatus Tbe Heart Cardiac Sounds, Movements, and 

 Impulse Rhythm of the Heart's Action Pressure of Blood in the 

 Heart's Cavities The Arterial Circulation Movement of Blood through 

 the Arteries Arterial Pulse Equalization of the Arterial Blood Current 

 Arterial Pressure Rapidity of the Arterial Current The Venous 

 Circulation Movement of Blood through the Veins Rapidity of the 

 Venous Current The Capillary Circulation Capillary Blood- Vessels 

 Movement of Blood in the Capillary Vessels Physical Cause of the 

 Capillary Circulation Velocity of Blood in the Capillaries General 

 Rapidity of the Circulation Local Variations in the Capillary Circula-
