Gas exchange is important as it is the transfer of oxygen from the surroundings to individual cells in the body, required by the cells for respiration. This process produces energy, essential for the organisms survival. A waste product of respiration is carbon dioxide, which if not removed from the body by gas exchange, will be harmful.

Folded out completely, they would cover an area the size of a tennis court! This allows several litres of carbon dioxide and oxygen to diffuse into and out of the lungs.

∙ 12y agoSurface area is important for gas exchange. Extended surface area is required to increase the capacity for gas exchange to tale place. This is because large surface area provides more space for gases to diffuse across.

∙ 12y agoGas molecules need to stick to a spot on the surface, inside or outside, for an exchange to occur. If a spot is already occupied, then the available surface area is smaller by one spot and its immediate surrounding (molecules of the same gas repel each other slightly, in general). Even if the spot is occupied with the right gas molecule on the outside, the inside spot may not be occupied with the correct counterpart. A larger surface area allows a better chance of the right molecules occupying opposite sides of the surface for an exchange to occur.

What provide the greatest surface area for gas exchange?
Gas exchange occurs in the alveoli of the lungs.
How does gas exchange take place?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
Explain why large active organisms need special surface for exchange?
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.
What is the stomata for?
Stomata is a tiny opening or pore, found mostly on the under-surface of a plant leaf. It is responsible for gaseous exchange between the leaves of plants and the environment.
Is gas exchange the same thing a respiration?
inhalation and exhalation takes place in respiration.Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.therefore they both are same things.
What provides a large surface area for gas exchange?
Your lungs provide a very large surface area for gas exchange.
What happens if the surface area of the respiratory membrane decrease in gas exchange?
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
Why are the bronchiole walls folded?
To increase surface area for gas exchange.
The greatest surface area for gas exchange occurs within the?
alveoli of the lungs. These tiny sacs are surrounded by a network of capillaries, allowing for efficient exchange of oxygen and carbon dioxide between the air and the bloodstream.
The folds of the inner sac provide what?
Folds increase surface area and therefore a greater surface area for gas exchange
The feathery structure of gills aid in the function of gas exchange by?
it increases surface area for gas exchange which means that more oxygen is absorbed.
Why do alveoli die in emphysema?
Destruction of alveoli reduces the surface area for gas exchange
How can capillaries allow gas exchange?
Large surface area + small radius for diffusion.
What does the capillary network in each gill filament provide?
A high surface area for gas exchange.
Where in the lungs does gas exchange happen?
AlveoliGaseous exchange takes place in the alveoli of the lung
The efficiency of gas exchange in the lungs of vertebrates is greater because of what?
The efficiency of gas exchange in the lungs of vertebrates is greater because it increases the lungs' internal surface area.
What provide the greatest surface area for gas exchange?
Gas exchange occurs in the alveoli of the lungs.
