How does venom work?

Answer:
It depends what type of active ingredients are in the venom. Venom generally falls into one of two groups - Haemotoxins or Neurotoxins. Haemotoxins attack the blood stream, causing blood to clot or breaking down the blood vessels so the victim literally bleeds to death. Neurotoxins work on the nervous system, paralysing the victim, or shutting down the respiratory system.
