absence or failure of digestive system

[sqad617]

So, what is your question?

[schmoggie]

lack of a bodily system, part or function is known as atresia, but this is a very far-reaching term.
I think the term digestive atresia is sometimes used.

[schmoggie]

sorry, I did not make myself very clear. I meant that the term atresia as applied to the digestive system might have to be qualified in relation to the specific nature of the lacking or failed parts of the digestive system
