Your lungs have very large surface area. About 100 square meters or 1100 square feet.
no, they do not lungs are much larger
Your lungs provide a very large surface area for gas exchange.
Lungs
Large surface area
By providing a large area in the lungs.
The larger the exposed surface area - the faster evaporation occurs.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
It is the area of the exposed surface. So if you take a cube, the surface area is the sum of the areas of each of the 6 faces. They are all the same in the case of a cube. In general, add up the surface area of each exposed surface and this is the total surface area.

Surface Area
According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to adjust. There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m2.
