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.
The respiration system adopts to the surface area to volume ratio to help the exchange of gases.
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
Surface size directly affects the possibility for gas exchange. Volume affects how much the cell can contain. If a cell has a large volume and a small surface area, it will be able to keep in water easily. But if it needs outside gas input for its reactions, the small surface area may be a limiting factor.
large area
Your lungs provide a very large surface area for gas exchange.
Large surface area + small radius for diffusion.
they have a large surface area, a good blood supply close by, thin walls (often only 2 cells thick) and are moist. This all aids in effective gas exchange.
By providing a large area in the lungs.
AlveoliGaseous exchange takes place in the alveoli of the lung
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.

I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
They Have A large surface area and they are full of red blood cells
provides a large surface area for exchange in oxygen and gas?
You have barile? Lungs have hierarchical structure which minimizes volume but maximises surface area Aveoli are the smallest units of structure and are the site of gaseous exchange: - They are circular = max surface area for min volume - Their most surfaces faciliate the exchange of gases - They have extensive blood supply which also faciliate the exchange
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
