ANATOMIC ARRANGEMENT OF THE BODY 19 



Splanchnology : the anatomy of the internal organs 

 digestion, respiration, etc. 



The construction of each organ and portion of the 

 body, and its independent function, as well as the 

 combined actions of several organs entering into 

 the performance of a definite act, as in digestion, etc., 

 are described under the term physiologic apparatus. 



Digestive apparatus, by means of which food isdigested. 

 Absorptive apparatus, for the absorption of nourishment 

 into the lymph and blood. Circulatory apparatus, for 

 the distribution of blood from the heart to all portions 

 of the body. The respiratory apparatus, by means of 

 which oxygen is absorbed into the blood from the air 

 breathed into the lungs, and carbon dioxide and other 

 waste materials are given off from the blood to the 

 atmosphere. Urinary apparatus, for the elimination 

 of waste materials from the body through the kidneys 

 and bladder, as urine. Secretory and perspiratory 

 apparatuses the former secreting essential materials 

 for the maintenance of body nutrition; the latter 

 aiding in regulating heat dissipation and in eliminating 

 waste materials through the sweat glands of the skin.
