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

'and use lungs' is the definition.
I can't tell whether this definition defines the answer.

'live having received new heart' is the wordplay.
'live' becomes 'be' (synonyms).
'having received' is an insertion indicator.
'new' indicates anagramming the letters.
'heart' anagrammed gives 'reath'.
'be' placed around 'reath' is 'BREATHE'.
