10 SUMMARY. 



The things going to make up the body and capable of 

 being burned are known as animal matters; the ashes are 

 mineral matters. In every tissue of the body there are 

 water, animal matter and mineral matter. In some a 

 great deal of water, as in the blood; in others a great 

 deal of mineral matter, as in the bones and teeth, which 

 owe their hardness to lime; in still others a great deal of 

 animal matter, as in fat and muscle: but everywhere 

 some of all three. 



18. Summary. Anatomy is concerned with the form 

 and structure of the parts of the body. 



Physiology with the uses of the parts and the ways in 

 which they work. 



Hygiene with the conditions of life which promote the 

 health of the body. 



The materials of the body are hard or soft, solid or 

 liquid, and are fitted for different purposes. 



Tissue is the name given to each of the materials, 

 whether blood, bone, muscle, fat, or any other. 



The organs are formed of tissues combined in various 

 ways. Each organ has its own particular duty, or func- 

 tion, which in health it performs in harmony with all the 

 others. 



Vertebrates are animals having back- bones such as 

 man, beasts, birds, reptiles, and fishes. Their bodies 

 contain two main cavities, dorsal and ventral. In the 

 dorsal cavity are the brain and spinal cord. The ventral 

 cavity contains lungs, heart, stomach, liver, intestines, 

 and kidneys.

 the organs ? Of vertebrates ? Of invertebrates ? Of mammalia ? Of 

 the chemical constituents of the body?
