Coeliac (solar) plexus

Looks like

A web of nerve fibres and knots around the origin of the main gut artery.

What it does

Controls gut blood flow, movement and secretion without your thinking about it.

Keeping it well

Nothing routine. Pain from pancreatic disease is sometimes treated by blocking this plexus.
