What is the process of defecation?

Defecation is the final step in the digestive process that removes all undigested materials from the body. Defecation involves both voluntary and involuntary actions. When feces fills the rectum, it triggers the defecation reflex. The urge to defecate can be controlled in most individuals except young children and others who have suffered spinal cord injuries.
