Body part shaped from bowel (5)

I believe the answer is:

elbow

I'm a little stuck... Click here to teach me more about this clue!

'body part' is the definition.
(elbow is a kind of body part)

'shaped from bowel' is the wordplay.
'bowel' anagrams to 'ELBOW'.
Though, I'm not sure how this is indicated.

Can you help me to learn more?

(Other definitions for elbow that I've seen before include "Sharp bend in a road or river" , "Nudge" , "Hinge joint" , "given to one about to leave" , "Sort of grease" .)

I've seen this clue in the Sydney Morning Herald.
