ANATOMY AND PHYSIOLOGY. 



our first duties to learn enough about our bodies to be 

 able to avoid doing things likely to harm them, or neg- 

 lecting to do that which is for their welfare. 



2. What Anatomy is. We could not look at the watch 

 without seeing that it was made up of different pieces, as 

 case, and face, $iid hands; and a glance at the works in- 

 side w<?ulc! shpw> us that dozens of parts, such as wheels, 

 rid< pivots, arid- springs, and screws, without which the 

 portions we see on the outside would be useless, were 

 fixed together in a special way to make the watch. 



Likewise, on looking at the outside of the body you 

 easily perceive head, and neck, and trunk, and arms, and 

 legs; and if you could see into the inside you would find 

 hundreds of other parts, which move the parts you see 

 and make them useful. The science which teaches us 

 the shape and size of all the parts of the body, where 

 they are placed in it, and how they are joined together, 

 is named Hitman Anatomy. 



3. What Physiology is. On examining the parts of 

 which a watch is made we find that each has its use: the 

 case to protect the works, the glass to let us see the face 

 and yet keep out dust, the hands to show the hour, the 

 spring to keep it going, and so forth. 



In like way it is found that the various parts of the 

 body have their uses: as the eyes to see, the mouth to 

 eat, the legs to walk with. The science which teaches 

 the uses of all the parts of the body, more particularly of 

 its inner parts, is named Human Physiology. 



2. What do we easily find out on examining a watch? In this re- 

 spect how may the body be compared to a watch? What is Humai. 

 Anatomy ? 



3. Why are there many parts in a watch ? In the body? What is 

 Human Physiology ?
