it is expelling unused matter from the body. This is different from excretion, which is expelling leftover and waste chemicals from the body.
Basically: defecation is egeston 9the body simply expels what it doesn't absorb) ,perspiration and urination are excretion (the body expels excess salt, uric etc)

Ingestion is taking things into an organism from the enviornment, egestion is the opposite.

Egestion
The expulsion of excess and unused food from within the body.
The process by which undigested food (waste) is gotten rid of in the form of faeces. *Not to be confused with excretion*

Animals/humans that ingest bulk food unavoidably take in some matter that they are incapable of using. In the case of unicellular organisms that form food vacuoles eventually fuse with the cell membrane and then rupture, releasing indigestible wastes to the outside. Substances that cannot be digested, such as cellulose, pass into the colon/large intestine. Then, in due time the body secretes/defecates the waste material.
