ateriosclerosis.

so there was a question on the study guide and i think the answer was either arteriosclerosis or artherosclerosis, but i am not sure which, and they are both very similar. so i just hope there aren't any questions on the test about them. on some web sites when you look up arteriosclerosis it has in () artherosclerosis right next to it showing that they are actually the same thing, so, yeah, they are just really confusing if we need to know the difference between the two.
