Antrum

Looks like

The narrowing lower third of the stomach, leading towards the outlet on the right.

What it does

Grinds food into a paste and releases gastrin to drive acid production.

Keeping it well

The usual home of Helicobacter pylori, a common cause of ulcers and stomach cancer; a breath or stool test finds it and antibiotics clear it.
