Why is surface area of alveoli in lungs is greater than the surface area of the skin?

The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.

What would the surface area of all the alveoli in the lungs be in square meters?
Vh
What organelle has a large amount of surface area?
The Alveoli
How does surface area to volume ratio affects an organism?
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.
Does a planet with greater mass have greater surface area?
A planet with a greater mass does not necessarily have greater surface area than one with less mass. The planet could be made of denser material and have a smaller surface area. Mass doesn't always mean volume.
Which is true about the volume or surface area of these prisms?
You must be with K12 if you are it is The surface area of A is greater than the surface area of B.
Why alveoli so small and uncountable in number?
The small size, coupled with the vast amount of alveoli - means that the body can absorb much more oxygen than if our lungs were simply two huge 'empty bags'. The surface area is far greater in our lungs because of the number of alveoli.
What would the surface area of all the alveoli in the lungs be in square meters?
Vh
What organ does oxygen pass from into the capillaries?
I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
Where in the lungs does gas exchange happen?
AlveoliGaseous exchange takes place in the alveoli of the lung
Why does the lungs have many alveoli?
it is so to increase the surface area for more exchange during oxygenation.
What is the part of alveoli in our body?
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood - also known as gaseous exchange. The alveoli have a very large surface area - in fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres - it is another example of the importance of the surface area- to-volume ratio. If your lungs were simply two large balloon-like structures, the surface area wouldn't be big enough for you to get enough oxygen by diffusion to supply the needs of your cells. But each alveolus is a very tiny sphere. The smaller the radius of a sphere, the bigger the relative surface area - halving the radius increases the relative surface area by a factor of four. The millions of tiny alveoli in the human lungs are a very effective adaptation which provides a huge surface area for gaseous exchange into and out of the blood. The alveoli have a good air supply from the bronchioles and a rich blood supply. This is vital for successful gaseous exchange because it maintains a steep concentration gradient for oxygen from the air in the alveoli to the blood, and for carbon dioxide from the blood to the alveoli.
Why does the alveoli need such a big surface area in the lungs?
because it needs to move in its own space is well.
What provide the greatest surface area for gas exchange?
Gas exchange occurs in the alveoli of the lungs.
How does the reduced number of alveoli affect the xchange of oxygen and carbon dioxide?
the coughing causes the walls of some of the alveoli in the lungs to burst. when this happens the surface area of the lungs in contact with the air is reduced.
What are Tiny sacs in the lungs called?
alveoli
Why are there many small alveoli in the lungs instead of a few large ones?
There are many little air sacs instead of big air sacs because in order to breathe you have to have air sacs spread around the whole entire lungs to breathe correctly! HEHE!! COES REPRESENT!! Frederika Rubio rm.22 Mrs.Feinberg
Tiny air sacs in the lungs?
They're called alveoli, they increase your lung's surface area and operate the exchange of gasses in and out of your blood. hope that helps.
