II. PHYSIOLOGY 



1. Processes Pertaining to Food. 



(a) Ingestion (taking in food). 



(b) Egestion (throwing out undigested food). 



(c) Digestion (fermentation of ingested substance brought 

 about by various secretions). 



(d) Absorption (passing of digested food by osmosis through 

 body membranes and making use of inspired oxygen). 



(e) Circulation (carrying absorbed substance to all parts of 

 the body). 



(f) Assimilation (the conversion of absorbed non-living mat- 

 ter into protoplasm). 



(g) Growth (the increase in size due to additional protoplasm 

 being made). 



(h) Reproduction (the production of new organisms similar 

 to the parent). 



2. Processes Pertaining to Oxygen. 



(a) Inspiration (taking in oxygen which aerates blood as it 

 passes through lungs). 



(b) Oxidation (burning of ingested food). 



(1) Secretion (pouring out substances to be used again). 



(2) Expiration (throwing out C0 2 ). 



(3) Excretion (throwing out used substances in the form 

 of urea, uric acid, etc.).
