Is God the Son's blood divine and infinite or human and finite (Western Catholic)

This question is related to https://christianity.stackexchange.com/questions/56667/was-god-the-sons-blood-divine-and-infinite-or-human-and-finite-protestant-inte , but I didn't realize there may be different interpretations. My question concerns whether God the Son's blood is human or divine. If human, then I don't understand how it was infinite enough to be an acceptable sacrifice, why he needed to be God, and how this is not an abomination. If divine, then it must carry the supposed qualities of divinity (infinite, eternal, and unchangable) so that he was not a real human. According to Western Catholic trinitarianism, when God the Son's blood was shed, was this a shedding of human, finite blood, or was it divine, infinite blood?
