Digestive system
Looks like
A thick ring of muscle at the outlet of the stomach, where it joins the duodenum.
What it does
Lets food through a little at a time and stops bile flowing back.
Keeping it well
In babies of a few weeks a thickened pylorus causes forceful projectile vomiting after every feed, which needs same-day assessment; in adults ulcers or cancer can narrow it.
