'Kaya-sankhara' in Anapanasati & Paticcasamuppada? Are they related?

The term 'kaya-sankhara' is defined in MN 44 as the 'in & out breathing'. The same term is found in step 4 of Anapanasati & in the 2nd nidana of Paticcasamuppada, as follows: > *He trains himself, 'I will breathe in calming kāyasaṅkhāraṃ. 'He trains himself, 'I will breathe out calming kāyasaṅkhāraṃ.' > Anapanasati Sutta* ~ > *And what are saṅkhārā? These three are saṅkhārā: kāyasaṅkhāro, vacī (verbal) saṅkhāro, citta (mind) saṅkhāro. These are called saṅkhārā. > Paticca-samuppada-vibhanga Sutta* My questions: 1. Does 'kaya-sankhara' have the same meaning in both contexts, i.e., in & out breathing? 2. If not, is there another alternative definition apart from in MN 44? 3. If not, is it possible for both contexts to have the same meaning?
