She lived a happy life.

She [topic-は] happy human-life [object-を] sent.
人生 ('human life, life as a whole') is the philosophically weighty word for the entire span of one's existence — distinct from 生活 ('daily living, lifestyle'). When Japanese reflects on life's meaning, it usually says 人生; when it talks about routines, it says 生活. Pairing 人生 with 送る yields 'live out one's life,' a slightly grander construction than 生活を送る. The same 送る ('send') threads through both.
