Question

Arrange the sequence of events in correct order that take place after we ingest food.

• A. Digestion, absorption, assimilation, egestion
• B. Absorption, egestion, assimilation, digestion
• C. Assimilation, absorption, egestion, digestion
• D. Egestion, assimilation, absorption, digestion

Answer 1

The correct option is A Digestion, absorption, assimilation, egestion

• Food is taken into the digestive system through the mouth by the process of ingestion.
• These food particles are further broken down into simpler forms by the process of digestion with the help of enzymes.
• Once digested, vital nutrients are absorbed by the body by the process of absorption.
• Digested nutrients are then utilised for various purposes. This process is called assimilation.
• Finally the undigested portions are eliminated from the body by the process of egestion.
