The total length of the blood vessels in the body is roughly 100 000 km. Most of this length is due to the capillaries, which have an average diameter of 6.90 μm. Estimate the total volume of blood in the human body by assuming that all the blood is found in the capillaries and that they are always full of blood.

Capillaries, the smallest blood vessels of the body, connect the arterial system with the venous system and supply our tissues with oxygen and nutrients. It is estimated that if all of the capillaries of an average adult were unwound and spread out end to end, they would extend to a length of about 64,000 km. How many miles is this length? Compare this length with the circumference of the Earth

The total length of the blood vessels in the body is roughly $100000 \mathrm{km} .$ Most of this length is due to the capillaries, which have an average diameter of $8 \mu \mathrm{m}$. Estimate the total volume of blood in the human body by assuming that all the blood is found in the capillaries and that they are always full of blood.
