DIGESTION OP FOOD. 365 



The blood-vessels of the stomach and. intestine and the villi 

 of the latter receive the digested food for further elaboration 

 (absorption). The undigested remnant of food and the excre- 

 tions of the intestine make up the faeces, the latter being ex- 

 pelled by a series of co-ordinated muscular movements essen- 

 tially reflex in origin.
