The function of rectum is to store the feces temporary before it is excreted out from the human body.
Explanation:
The end part of large intestine is called rectum and it is connected to the anus. The distal part of rectum is called ampulla and feces is stored here temporarily. When stored feces increases its walls expand. There are receptors present in its wall that send a signal to the brain and feces is discharged out of the body.
