All elements heavier than iron supposedly came from Supernovas. Long, long ago, in a galaxy far, far away....

First of all, I would like to know your definition of "heavy elements" from an astronomical perspective, that means EVERYTHING other than helium!
If you mean how do they get into the body as opposed to where do heavy elements come from in general then mainly swallowing or inhalation.
Most of them are swallowed - either as part of our food or part of our drink. Some, like lead, can also be inhaled (esp in the days of leaded petrol etc)
We take in many metals from our food, iron from read meats, zinc from most shellfish.
If you have mercury amalgam fillings then guess what else leaches out over the years into your system.
Some of these heavy elements do NOT easily leave the body and can accumulate to dangerous levels, most do not harm.
A process called chelation can be used to remove some heavy metals from the body - google for it if you wish for more info on this - a bit long winded to go into here.
If you meant any elements in particular, then please post a slightly more explanatory question. If not, hope the answer is of use.

The heavy elements were generated in stellar explosions ( super nova).

WE are all made of star dust.
