Go Term Hierarchy -- How To Find All Children Terms From A Parent Term?

Question

[JacobS]

I have a question regarding gene-ontology term relatedness. Say I have a GO term like GO:0044238, which signifies "Primary Metabolic Process." How can I pull all GO terms that are children of this term? If I use tree view, I can see this view:

Primary metabolic process: - cellular amino acid metabolic process - TCA cycle - protein metabolic process

...and beneath protein metabolic process are the following: - proteolysis - lipoprotein metabolism

I want to mine every GO term that is a child of Primary metabolic process at every level. Thanks for any suggestions!
