Different poisons work in different ways, here are a few examples:
The man-made nerve agents created during and after world war two: These mess with your nerve signalling pathways which leads to some severe and horrible symptoms and quite quickly death.
Cyanide: Found in tiny doses in apple pips (but don’t worry, the dose is far too small to hurt you, ever!) but inhaling a large dose of hydrogen cyanide gas (HCN) is instant death. Cyanide displaces oxygen in your cells.
Foxgloves (Digitalis): Those lovely plants in peoples gardens. These contain a toxin called digoxin which changes the concentration of sodium ions in your blood which causes problems in the way the heart functions.
Snake venom: Different venoms work in different ways but sometimes snake venom can turn your blood into jelly (coagulation). Nasty!

Because you’re a big bag of chemicals with a brain, and if any of the chemicals stop doing their job then the whole thing stops working. Poisons are chemicals that either replace the chemicals in your body, which stops the replaced ones from being able to do their job, or they react with the chemicals in your body and mean that they aren’t there at all any more.
