Want this question answered?
because the walls are thin
Yes most gases do.
Liquids and gases can be categorized differently through many ways, specially through their partcile composition. Liquid particles are close together and pass pass each other easily. In the other hand, gas particles are well separated and have lots of free space to move at high speeds.
Any gas that does not substantially dissolve in or react with water can pass through it. This group includes air (except for its carbon dioxide content), all the noble gases, and all the hydrocarbon gases.
they pass through channels in the cell membrane
alveolus (alveoli)plural. it's purpose is to exchange gases between the air and the body.
It is easy for air to pass across the wall of an air sac because the wall is thin.
because the walls are thin
3 or 4
The answer is two cells. Alveolus is having single flat cell wall and the capillary having the single flat cell wall.
Lenticels allow gases to pass through them. Hope this helped. Gigi

blood does not pass across the placenta
because the oxygen needs to pass through alveoli and there is alot of cells around to be transported!!
No, gases do.
