Circulation

How blood actually moves around your body, and what happens when it cannot.

Your circulation is one continuous system. The same vessels that feed your heart run to your brain, your kidneys, your gut and all the way down to your feet, which is why a problem in one place so often says something about the others.

That is also the useful part.

What protects the vessels in your legs is mostly what protects the ones around your heart.
