Question : Give explanation: (1) Assimilation (2) Egestion

Answer»

Solution :(1) Assimilation: The absorbed SUBSTANCES finally reach the tissues which utilise them for their activities. This PROCESS is called assimilation.
(2) Egestion : The digestive wastes solidified into COHERENT faeces in the RECTUM initiate a neural reflex causing an urge or desire for its removal.
The egestion of faeces to the outside through the anal opening is a voluntary process and is carried out by a mass peristaltic movement.
