- So arteries are blood vessels
that transports oxygenated blood from your heart
to the rest of your body.
And they're important because obviously,
all the cells in your body need oxygen.
But they're important
because they regulate the blood flow as well.
They typically need to be replaced
if there's a disease caused by genetic factors
or poor health or lack of exercise.
You can get high cholesterol that can then form plaques
and then end up clogging the artery.
And so at that point, they need to be,
either have a bypass surgery or replaced.
