Can alveoli surface area cover a football ground?

No, the alveoli surface area cannot cover a football ground. Although the alveoli have an extensive surface area, it is not as large as a football ground.

The total surface area of the alveoli in the human lungs is estimated to be around 100-140 square meters, which is about the size of a tennis court. A football ground, on the other hand, is typically around 7,140 square meters, which is significantly larger than the surface area of the alveoli.
