Why must air sacs have thin walls?
The air sac must have thin walls so that air passes easily through it.
Do alveoli have very thick walls?
No, alveoli do not have very thick walls. In fact, they have very thin walls composed of a single layer of epithelial cells, which facilitates efficient gas exchange between the air in the alveoli and the blood in the surrounding capillaries. This thin structure allows oxygen to diffuse into the blood and carbon dioxide to diffuse out easily.
For air sacs to do their job their walls must be kept?
lubricated
Is the air in the thermosphere thin or thick?
The air in the thermosphere is very thin because of it's high altitude.
What layer of the atmosphere is the air very thin and has little moisture?
The layer of the atmosphere where the air is very thin and has little moisture is the mesosphere. This region is located above the stratosphere and below the thermosphere, and it is characterized by low temperatures and a decrease in air density.
Why do lungs have thin permeable walls?
diffusion of gases (oxygen and carbon dioxide) to & from air in lungs and capillaries in alveoli
What is the air like at the top of a mountain?
The air is usually very thin at the top of a mountain.
What does it mean when a tear drop drops out of thin air on your cheek?
Their must be a very unhappy bird flying past. Just kidding, the definition if 'thin air' implies it came into existence from nowhere, which is a bit improbable. My explanation is that it was a drop of water (rain, vapour, roof etc)
Why are planes limited in altitude?
Because the higher you go the more thin air. So the engines have to work very hard to suck air in their engines dues to thin air and less air.
What is a very thin MacBook that is a three letter word?
MacBook Air
How are the alveoli designed to maximise the exchange of gases?
the paouch like air secs at the smallest lenchioles is called alveoli.the walls of alveoli are very thin and they are sorrounding thin blood capllaries .it is in alveoli exchange of gaseouse takes place there are so many alveoli in blood so they provides very larges surface srea for cxchanges of gaseouse
How much air is at the top of mount Everest?
The air at the very tip is really thin, and not enough to survive mostly.
