This video below explains a little bit about not only the special effects behind the Alien chest scene itself (btw, if you haven't seen the scene: the stomach is fake), but also the interactions of screenwriter Dan O'Bannon, Ridley Scott, and the late H.R. Giger, the much-lauded special effects man who visualized most of what we now know as Alien, leading up to the scene itself. Some parts of the scene were a surprise to the actors involved, contributing to its frenzy--other parts required Herculean, meticulous planning. It's important to watch little films like this because it's important to know that what you're watching on the big screen takes extensive cooperation between numerous individuals before it reaches you, in your seat, and a more private, personal cooperation, that of the viewer and the work, begins.. .
