When the volume of the thorax increases,........
The volume of the thorax decreases
The pressure in the lungs decreases
The pressure in the lungs increases
There is no change in pressure
When the diaphragm relaxes,.....
The volume of the lungs increases and the pressure increases
The volume of the lungs decreases and the pressure increases
The volume of the lungs decreases and the pressure decreases
The volume of the lungs increases and the pressure decreases
In what ways is the bell jar demonstration different to ventilation the lungs? (check all that apply)
The glass does not move like the ribs move
The bell jar does not respire
The first tube then splits into two tubes
There are no intercostal muscles
What makes a good exchange surface? (check all that apply)
A large surface area
A thick barrier
A good blood supply
A moist surface
A large surface are means.......
A good concentration gradient
More space for diffusion to occur, so less diffusion
Less diffusion
More space for diffusion to occur, so more diffusion
A good blood supply means........
A large surface area is needed
The area is moist
A concentration gradient can be established
Less diffusion will occur
A moist surface means.....
Gasses can dissolve in solution
The area is slippery for exchange
The large surface area is wet
Less diffusion will occur as the water is a barrier
A thin barrier for diffusion; one cell thick, means......
The diffusion distance is smaller, so the rate of diffusion is slower
The diffusion distance is smaller, so the rate of diffusion is quicker
The rate of diffusion is unchanged as the molecules will still move
Molecules are unable to diffuse over cells
Gas exchange in humans is.......
When breathing occurs
When carbon dioxide moves out
When oxygen moves in
The exchange of oxygen and carbon over a surface
