your final stop for waste removal
THE RECTUM + aNUS
Think of the rectum as your body’s storage drawer and the anus as the exit door.
The rectum holds waste until it’s time to go, and the anus controls when (and how) it leaves.
While they don’t get much attention, these structures are essential for controlling bowel movements and keeping your digestion running smoothly.
Your rectum + anus:
Store solid waste (feces) until it’s ready to be passed
Signal your brain when it’s time to go
Control the release of stool with the help of muscles (sphincters)
Maintain continence (prevent accidental leakage)
Support the final stage of digestion by eliminating waste products
RECTUM + ANUS BASICS
Common Terms + Simple Definitions
Here’s a mini glossary for rectal + anal related words you’ll see throughout the site:
Rectum - The last section of the large intestine where stool is stored
Anus - The opening where waste leaves the body
Sphincter - A circular muscle that opens and closes to control stool release
Internal Anal Sphincter - Involuntary muscle that helps keep the anus closed
External Anal Sphincter - Voluntary muscle you control to release stool
Defecation - The act of passing stool
Continence - The ability to control bowel movements
WHAT THE RECTUM + ANUS WORKS WITH
THE rectum + anus + OTHER SYSTEMS
Large Intestine → Passes solid waste into the rectum
Nervous System → Sends “time to go” signals and helps coordinate muscle control
Pelvic Floor Muscles → Work with sphincters to control elimination
Brain → Decides the appropriate time and place for bowel movements
Blood Vessels → Supply oxygen and nutrients to tissues
A healthy RECTUM + ANUS:
Allow controlled, comfortable bowel movements
Prevent accidental leakage or urgency issues
Help signal when your body needs to eliminate waste
Support digestive comfort and gut health
Problems in this area — like constipation, hemorrhoids, incontinence, or anal fissures — can significantly affect daily life and overall well-being.
Taking care of your digestive health, staying hydrated, eating enough fiber, and keeping pelvic floor muscles strong all help these final-stage organs do their job.
