digestive system of human consists of 5 components
1.ingestion
2.digestion
3.absorption
4.assimilation
5.egestion

1. In ingestion one must put the food in his/her buccal cavity
2. In human beings digestion starts from mouth itself by saliavay amylase. As the food rushed down the Oesopaghus and collects into the stomach their various enzyme secretion is done such as pepsin,mucus,HCL,secretin,etc.
then the food passes into the small intestine where microvilli absorb nutrients from ingested food
later the digested food is passed into large intestine for water absorption.
4. Assimilation defines the process of blood carrying the absorbed nutrients throughout the body
5. And finally unwanted waste is removed in egestion.
