OUR BODIES AND HOW WE LIVE 



The part of the throat directly opposite the line of vision, 

 as we have learned, is the back wall of the pharynx, which 

 continues downward to form the gullet, or food passage. 

 The pharynx runs up to the base of the skull behind, 

 and ends in a kind of vaulted roof 

 bent somewhat like a crooked 

 forefinger. 



Experiment 79. Study the general 

 construction of the throat by the help 

 of a hand mirror. Also examine the 

 throat of some friend. 



Experiment 80. To show the con- 

 struction of the vocal organs. Secure 

 and examine the windpipe of a sheep 

 or a calf. It differs somewhat from 

 the vocal organs of the human body, 

 but it will enable us to recognize the dif- 

 ferent parts which have been described. 

 A suitable specimen can easily be ob- 

 tained from a butcher.
