Where does carbon dioxide exchange with oxygen?
they exchange in the aveoli and capillaries

What is fumed glass?
glass with an iridescent surface due to a thin film of metallic oxides
Why do the weight of gold reduces after polishing?
Polishing removes an extremely thin layer of gold off the surface.
How can aluminum foil float in water?
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
Why do the walls of the capillaries and aveoli need to be thin?
The walls of alveoli are thin to allow the exchange of gases (Co2 and O2) between blood capillaries and the aveoli in the lungs.
Name the slippy secretion that keep the alveolar walls from sticking together?
Pulmany Surfactants. This is accomplished by lowering the surface tension in the aveoli. When the surface tension in the aveoli is decreased it allows for easier reinhilation of the aveoli because there is less work required to do reinflate them.
Tiny sacs within the lungs which increase the respiratory surface?
the aveoli
What cause distruction to aveoli?
Aveoli can be damaged by obsessive smoking and general air pollution from burning fossil fuels (Such as coal). When aveoli is damaged, it loses surface area and therefore you cannot absorb enough oxygen to keep yourself healthy.
Can a person live on two aveoli?
No, we need many, many alveoli to give the surface area needed for gas exchange.
What absorbes oxygen from the air?
the aveoli in the Lungs
What happens between the aveoli?
how does the exchange of gasses between the aveoli and blood happen
Is the aveoli an organ?
no cause aveoli are little air sacks in the lungs. they are not an organ they are in an organ.
What are the bubble shape sacs in the lungs where gas exchange takes place?
The thin sacs in the lungs where the gas exchange takes place are called aveoli.
What is the thin layer on earth's surface called?
Global Water
What is the purpose of the aveoli?
The alveoli are the sites of gas exchange in the lungs. They are round and numerous, so the surface area is maximised for increased volumes of oxygen and carbon dioxide to pass through. Their membranes are very thin, and they are surrounded by a network of capillaries to further increase the efficiency of the gas exchange process.
Do veins surround aveoli?
no
