Three main types of blood vessels – arteries, veins and capillaries carry nutrients, oxygen and waste throughout the body.
This set of vessels forms a closed system... nearly 100,000 km long!
The blood that circulates in the vessels is set in motion by the heart, a hollow, septated muscle that functions like a pump.
