Our circulatory system
Almost 74% of all blood vessels in our body are micro-vessels. If stretched out in one continuous path, they would amass more than 74,000 miles.
The circulation of our blood is the engine that keeps us going. The heart pumps blood through the main arteries, but it relies on the additional power of the autonomous pumping motion of the micro-vessels. It is these very small vessels that reach the most remote parts of our body.
