How many parts of the rocket are supposed to break off as it leaves earth orbit in apllo 13?

During the Apollo 13 mission, several components of the Saturn V rocket were designed to break off as it left Earth orbit. Specifically, the rocket consisted of three main stages: the S-IC first stage, the S-II second stage, and the S-IVB third stage, which would all separate at various points during the launch and ascent phases. Additionally, the Lunar Module (LM) and the Command/Service Module (CSM) would separate as the mission progressed. Thus, multiple parts were intended to detach throughout the mission.
