Heart & arteries
Looks like
The main stem of a coronary artery, from its opening in the aortic root before it divides; the left one is short (left main).
What it does
Carries all the blood that coronary artery sends into the heart muscle.
Keeping it well
Narrowing of the left main stem is high-risk and usually treated by bypass surgery or stent.
