Why does Atherosclerosis occur in arteries and not in veins?
Anupriyaganesh
Atherosclerosis occurs when LDL (Low Density Lipoproteins) get oxidized. Since the plasma in the arteries contains plenty of oxygen to oxidize the LDL's it occurs mostly in arteries. In the veins, there is little oxygen to be found, so it is much more likely to happen in the arteries for that reason.
