How do snake kill people

Not all snakes have venom. And not all snakes have the same venom. But it's what the venom kills you. If the snake has any venom. Now some snakes like the python or anaconda squeeze it's victim to death.

The snakes that have venom kill people cause the toxin in the venom is so strong that our human blood cells would die off cause the venom is attacking our blood which is causing that person to die but i agree with noah that certain snakes dont have venom
