“Get up” vs. “wake up” [closed]

(http://interactiveesl.files.wordpress.com/2012/10/wake-up-and-get-up2.png)

Sometimes there is a question,

“I am not a native English speaker. When I get up late in the morning, I get to inform my office that I am late for that particular day. And I am always confused if I should use "I just got up" or "I just woke up". Which one is it?”

Yeah as a non native speaker sometimes we still confuse about that phrasal verbs because the phrasal verbs is really close in Indonesian language, both of them in Indonesian mean “Bangun,” but we need to know and learn when the phrasal verb will be appropriate to use in our English sentence.

According to what I know when we wanna use "wake up" it means like when we opened our eyes from our dream, it doesn't matter you have getting up or not from the bed. But when we use "get up" it's mean you not lying/sitting any more. So, “wake up” is stop to sleeping and “get up” is to arise from bed or rise to one's feet). When people wake up, they get up. However, sometimes people just stay in bed. See this dialogue;

Person A: 'When did you get up this morning?'

Person B: 'I got up at 11.'

Person A: 'You slept at 11 last night. So you slept for 12 hours?'

Person B: 'No. I actually woke up at 9, but I just stayed in bed.'

And when you would ask someone when they woke up, you have to say “When did you wake up?” it’s incorrect when you said “When did you woke up?” Because the word woke up is referring to the past. It’s same with when we want to ask “When did you get up?” it’s incorrect when you said “When did you got up?”
