Does human ascaris know our anatomy?

I've read that it can run out when it faces bad conditions in our organism. How does it find a way out? Is it randomly checking every hole or what?

Your colon makes a way. Poop finds its way out, without checking every hole, why would ascaris be different?

What book are you reading which pops up so many questions?

A lot of parasites abandon ship if the host is stressed or nutrient deficient. But they don't "search" for a way out, but follow the same route that their natural reproductive cycle would take them. If they are intestinal parasites, it will be through the GI generally.

Another possible example of this is certain dormant viruses that reactivate when the host is weakened or sick. They probably reactivate because the immune system is compromised in a weak host, but it's possible as well, that it's a physiological cue to get out, because if the host dies, they go with it.

Having a mechanism in place to sence if the host is dieing and get out is clearly a survival tactic for a paracyte. Dead host equals dead paracyte. So this phenomenon would make evolutionary sence.
