<unk> s are often distinguished from other chemical agents due to their biological origin. According to an International Committee of the Red Cross review of the Biological Weapons Convention,<unk> s are poisonous products of organisms; unlike biological agents, they are inanimate and not capable of reproducing themselves", and "Since the signing of the Constitution, there have been no disputes among the parties regarding the definition of biological agents or<unk> s". According to Title 18 of the United States Code, "... the term<unk> " means the<unk>  material or product of plants, animals, microorganisms (including, but not limited to, bacteria, viruses, fungi, rickettsiae or protozoa), or infectious substances, or a recombinant or synthesized molecule, whatever their origin and method of production..." The word<unk>  does not specify method of delivery (as opposed to venom, a<unk>  delivered via a bite, sting, etc.). Poison is a related but broader term that encompasses both<unk> s and<unk> ants; poisons may enter the body through any means - typically inhalation, ingestion, or skin absorption.<unk> ,<unk> ant, and poison are often used interchangeably despite these subtle differences in definition. The term<unk> gen has also been proposed to refer to<unk> s that are delivered onto the body surface of another organism without an accompanying wound. A rather informal terminology of individual<unk> s relates them to the anatomical location where their effects are most notable: * Hemotoxin, causes destruction of red blood cells (hemolysis) * Phototoxin, causes dangerous photosensitivity * Hepatotoxins affect the liver * Neurotoxins affect the nervous system On a broader scale,<unk> s may be classified as either exotoxins, excreted by an organism, or endotoxins, which are released mainly when bacteria are lysed.
