As blood toxins or Hämotoxine (from ancient Greek αἷμα Haima , German , blood ' and τοξικόν Toxikon , German , Gift' ) are referred to substances whose chemical nature of the blood - blood coagulation or - hematopoietic system changed such that the transport and metabolic function is restricted or prevented becomes. The red blood cells and the bone marrow in particular are affected, which can damage the blood circulation and even lead to circulatory collapse .
A prominent example is carbon monoxide (CO). It prevents the blood from transporting oxygen by forming a stronger bond with hemoglobin than it does .
In contrast to the cell poison (some snake poisons , benzene or dioxins fall into this category), the cell is not damaged directly, but perishes from an insufficient supply of nutrients or oxygen.
Neurotoxins , on the other hand, work by means of - more or less destructive - interaction with the nervous system. Here are some drugs , but also curare and bufotenin ( arrow poisons ) or the poison of the fugu (a puffer fish).
