When you have multiple accounts in Apple mail you will have a single Inbox that includes all active email accounts, or by clicking the reveal arrow next to Inbox you can reveal the individual inboxes. Mail is really very flexible and allows lots of mix and match options. As Ira said setup is the same as on iOS devices. In fact with iCloud you can share the setup between OS X mail and your iOS devices.
