Arteriosclerosis is any hardening (stiffening) of artery walls. One of the ways this can happen is through atherosclerosis, which is when an atheroma (a build-up of dead RBCs,… fibres and platelets) begins to accumulate within an artery wall and may stick out into the lumen or even break through the endothelium. This makes the artery less flexible. So someone with arteriosclerosis does not necessarily have atherosclerosis, but someone with atherosclerosis must have arteriosclerosis, as their arteries have hardened.(MORE)
8--8 is 16. You use the "keep change change" rule keep the value of the 8, then change the minus sign to addition and the negative sign to positive, so basically what you ar…e doing is taking away a negative amount of w/e. Think about it that way and math will make more sense. Say you have 8 beans. If I take (subtract) away 8 beans you will have 0. But if i take away negative 8 beans I am giving you 8. Let's say your piggy bank has 8 dollars in it (+8). The only reason you have only 8 dollars is because your friend stole eight other dollars (-8). If you "subtract" that theft (i.e. you subtract the taken-away -8 by undoing it), the -8 goes away and you are back to +16. Hope that helps you to understand conceptually.(MORE)

Arteriosclerosis can lead to blood clots. Atherosclerosis is a plaque buildup which can lead to blockages in the arteries. Both conditions can easily be fatal. Blood thinn…ers are used to treat blood clots. Stents, balloon expansions, and bypass are used for atherosclerosis. (MORE)
