what path does a toxin take through your body? I know it is digested and absorbed into the blood stream by the small intestine but does it take a different path than food? Please help!

Didn't you answer this yourself? "I know it is digested and absorbed into your blood stream by the SI" Well since the toxin is absorbed into the blood stream it is then taken to the liver where it tries to filter the toxins so it will not harm your body. If too much toxin is injested your body reacts: example alchohol poisoning the liver cant filter all the alchohol so you get sick or vomit. Toxins are taken to the liver for this reason; it is a foreign substance your body doesnt know and it needs to be filtered so it cant hurt you.

That may answer your question.
