A REVIEW of the physiological processes which we have 

 thus far studied shows that the functions of the perfected 

 organism are divided into two great classes : 



The first class of functions may be grouped under the 

 general head of nutrition, taken in its widest sense. Nutri- 

 tion is common to animal and vegetable life ; and this is 

 sometimes called a vegetative process. 



The study of nutrition involves the following considera- 

 tions: First, the blood, which is the great nutritive fluid, 

 contained in the innumerable vessels which penetrate nearly 

 all of the tissues and organs of the body and are connected 

 with the system of lymphatic and lacteal vessels. Second, 

 the process by which the blood is circulated, sent by the 

 heart to all parts in the capillary system, used by the tissues 

 for their nutrition, then losing oxygen, gaining carbonic 

 acid, and being returned by the veins. Third, respiration, 

 the blood being freed from carbonic acid and getting a new 

 supply of oxygen in the lungs, by which it is rendered capa- 

 ble of again circulating through the general system. Fourth, 

 as the blood, in its passage through the capillary vessels, not 

 only loses oxygen, but is more or less impoverished by the
