Body part; case (5)
I believe the answer is:
chest
I believe this clue is a double definition.
'body part' is the first definition.
(I know that chest is a type of body part)
'case' is the second definition.
(I know that chest is a type of case)
(Other definitions for chest that I've seen before include "Piece of furniture" , "Large strong box for storage" , "Trunk or crate" , "Upper trunk" , "Part of body; storage box" .)
