Victory in southern cavities (5)

I believe the answer is:

veins

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

'cavities' is the definition.
The definition and answer can be both body parts as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'victory in southern' is the wordplay.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'southern' becomes 's' (abbreviation).
've'+'in'+'s'='VEINS'

Can you help me to learn more?

(Other definitions for veins that I've seen before include "Layers of ore" , "Characteristic styles" , "Blood vessels" , "Circulation aids" .)
