Objective: Illustrate how ingestion, absorption, assimilation, and excretion takes
place in the interaction of Digestive System with the Circulatory, Respiratory and
Excretory System.
Direction: Based from Activity 2, identify which digestive process takes place
such as Ingestion, Digestion, Absorption, Assimilation and Excretion. Choose the body
system involved in each process by using the following symbols:

Food is broken down into
