Renal arteries

Looks like

A short, wide artery from the aorta to each kidney, the pair carrying a fifth of every heartbeat.

What it does

Feeds the kidney and delivers the blood it filters.

Keeping it well

Blood pressure control; narrowing here causes high pressure that will not settle on tablets.
