The human body has about 96 000km of blood vessels.
The biggest blood vessel is the Aortic artery and delivers the blood from the left ventricle (heart) to the body. It is about 2.5-3.5 cm in diameter, and 30-40cm long.
The smallest blood vessels are called capillary, and are just 5-10 μm in diameter.
