The rectum is the final straight part of the large intestine before reaching the anus. The anus is the opening at the lower end of the digestive tract that controls the expulsion of feces. The rectum provides temporary storage for feces before they are expelled. As the rectal walls expand due to collecting feces, stretch receptors in the rectal walls stimulate the desire to defecate.
