Cells have to give up
Most poisons attack the body’s tiniest, yet most important building blocks: the cells.
The body contains trillions of cells, which control everything we do. But they are so delicate, even the tinest chemical change inside them can be fatal. This is essentially how poisons kill us.
Most of our cells have a nucleus surrounded by a number of other structures and encased in a membrane. The nucleus contains our DNA, and controls the cell. The membrane, on the other hand, contains a number of proteins, which open and close channels in the cell which allow other molecules and ions to flow in and out. This flow of molecules and ions is the foundation of our body’s functionality. Poisons disrupt this flow, which in turn prevents our cells from expelling waste, maintaing the right energy levels, or dividing. Too much disruption causes tissue and organ damage… and even death.
