Why doesnt the venom from a snake harm itself?

Answer 1

The venom is contained in a specific structure, the venom sac, which is designed to prevent the venom from reaching other parts of the snake's body, much as certain structures in our body, the gall bladder for example, contain substances which if released into the body in a nonspecific manner would be harmful. As for the snake consuming its venom along with its prey, snake venom is not harmful if ingested, either by the snake or by human beings, since it is a protein and would rapidly be broken down and digested in the digestive tract. However, most venomous snakes are not immune to their own venom, and if they accidentally bite themselves while chasing a prey animal, they may die from the bite.

Answer 2

Generally because the snake isn't in the habit of biting itself. Of course there are incidents of depression in laboratory pythons who will try to "fang out" the easy way, rather than endure the character building hardships of an incarcerated existence. The clever ones have to be restrained, defanged, and put into solitary confinement where some still find a way to fashion a noose out of their bodies and hang themselves.

Answer 3

If they weren't they would die from the venom building up in their bodies. They use it primarily to hunt, and so they were constantly be ingesting it. also of note is that if you were to drink venom it would probably not harm you nearly as bad as injecting it into yourself.

Answer 4

They are immune to their own venom.

Answer 5

Becuase they don't inject themselves with it.
