Blood is a fluid that circulates
around the body through the system of blood
vessels that includes
arteries, arterioles, capillaries, venules, and veins.
A typical human being has approx.
70 ml of blood per kilogram of body weight. So an average adult
male has approx. 5 litres of blood.
For more information about other components (or "constituents") of
blood, see the page about:
