Defecar é o ato de evacuar fezes do organismo através do relaxamento do esfíncter e contrações do reto anal. Existem vários reflexos fisiológicos que estimulam a defecação por meio do aumento do peristaltismo intestinal, entre eles estão o ortocólico, que acontece quando a pessoa acorda e se levanta, e o gastrocólico, que ocorre quando ingerimos algum alimento. A utilidade da defecação é fácil de ser compreendida: ela é necessária para a eliminação do material sólido não absorvido pelo organismo. Frequentemente, o ato de defecação é inibido por razões de ordem social.
