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.
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.
AlveoliGaseous exchange takes place in the alveoli of the lung
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.
Large active organisms need specialized exchange surfaces because their size requires a high surface area to volume ratio in order to efficiently exchange gases, nutrients, and waste products with their environment. Without these specialized surfaces, the transport of essential substances would be limited by diffusion and could not meet the demands of the organism's high metabolic rate.
I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
provides a large surface area for exchange in oxygen and gas?
They Have A large surface area and they are full of red blood cells
The function of alveuli is to provide a surface for gas exchange. Therefore, a large surface area means that there is a lot of area for the gas exchange to take place. Therefore it is to improve efficiency of gas exchange in the lungs (exchanging carbon dioxide for oxygen). The large surface area is due to the shape of the alveoli- the have many small "pockets".
Capillaries have thin walls that allow for diffusion of gases such as oxygen and carbon dioxide between the blood in the capillary and surrounding tissues. The close proximity of capillaries to cells ensures efficient exchange of gases due to a short diffusion distance. Additionally, the high surface area of capillaries facilitates a large area for gas exchange to occur.
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.
