If all arteries, veins, and capillaries of the human circulatory system were laid end to end, the total length would be 60000 miles, or 100000 km

The length is not meaningful. However, the surface area for gas exchange of an adult lung is about 200 square feet (19 to 20 sq meters)

If you take the lungs out and spread them, they would fill a tennis court.
