Larger cells have slower diffusion rates.
This is because the ratio of;
surface area of a cell : volume of a cell
Decreases with size, as volume increases exponentially with respect to surface area.
We might consider that;
Surface area = X²,
<em>Volume = X</em>³
As X increases, X² : X³ decreases.
So large cells have more trouble with diffusion.

Answer:
A healthy artery is wider and has no blockages. The lumen (which is the hole in the centre of the artery), is open and clear. This means there is more blood flow. An artery of a person suffering from coronary heart disease is often blocked, usually by a fatty deposit. This means the blood does not flow as well. (See diagram, in which I would draw two arteries, one with a blockage of fatty deposit, one clear and healthy).
