Trunk of left renal artery

Looks like

The main stem of the renal artery from the aorta to the kidney hilum, before it divides.

What it does

Carries all the blood to that kidney.

Keeping it well

Narrowed by plaque in older people or fibromuscular dysplasia in young women; stenting helps some cases.
