5 Questions
1 of 7
Name the 4 features of the alveoli helping to maximise the rate of diffusion
Lots of them + in a spherical shape ; Rich supply of blood capillaries ; Very thin alveolus wall ; Moist surface
2 of 7
Explain what each of the following features do to maximise diffusion...
.
3 of 7
Lots of them and of a spherical shape
Gives a relatively large surface area for diffusion ; Allows a lot of oxygen in ; So sides don't stick together
4 of 7
Rich supply of blood capillaries
Maintains concentration gradient ; Gas exchange takes place along the steepest concentration gradients possible
5 of 7
Very thin alveolus wall
Gives a short distance between air and the blood making diffusion easy
6 of 7
Moist surface
So sides of the alveoli don't stick together
