Venom
Venom is any of a variety of toxins used by certain types of animals, for the purpose of defense and hunting. Generally, venom is injected while poisons are absorbed by ingestion or through the skin.
Who Produce Venom:
The animals most widely known to use venom
are snakes, some species of which inject venom into their prey through hollow fangs; spiders
and centipedes, which also inject venom through fangs; scorpions and stinging insects, which
inject venom with a sting (which, in insects such as bees and wasps, is a modified egg-laying
device – the ovipositor).
Snake venom:
Snake venom is a complex type of saliva which
is produced and stored in glands under and behind the eye. It varies in protein and toxicity.
There are four types of venom: haemotoxic,
which attacks the blood; neurotoxic, which attacks the nervous system and causes paralysis; myotoxic, which destroys muscle tissue; and cytotoxic, which destroys other cells in the body.
