If you any active chemical in your system that alters the homoestasis, why does this chemical eventually leave the body? What prevents it from staying in the body forever?
In: Biology
They don’t. Lead notoriously bonds to the molecules in your skeleton and stays mostly for life. Many other toxic chemicals that have cumulative effects don’t get eliminated easily. Lots more compounds are “fat soluble” which means they will persist in your body fat for a long time, as opposed to “water soluble” things that get eliminated relatively quickly.
