Not consciously. Since they are not alive, they do not actually need brains to survive, it is simply an instinct. Therefor other bodily functions are sort of moot as well. If they eat enough, what they consume has to go somewhere. So I will leave the rest up to your imagination.

The zombies are really bad. They will do anything to try to eat your brains! To protect them, you have to kill them.
In popular culture, zombies are often depicted as craving brains, but this is not consistent across all zombie stories. The idea of zombies specifically eating brains may have originated from the 1985 film "Return of the Living Dead." In traditional folklore, zombies do not have a specific preference for brains.
This appears to be a conflation of two unrelated aspects of the original Romero zombies: they eat human flesh, and the only way to kill them is to destroy their brains.
