In between rounds she seemed more dazed then in pain. I wonder if it went numb or something because it appears she took a lot more shots after it was broken. 
She does spit out the water in a strange fashion between rounds. I can't stop watching the fight!
I remember when that college player's tibia shot thru his leg - he said it only hurt for a second, then it went that weird warm numb. Body was in shock, pain receptors blocked to maintain consciousness, etc etc.
Once her jaw was broken, maybe that jaw just hung, and she knew it was fcked up, but with tens of millions of $ on her staying undefeated, she just plugged thru it. Can't open mouth, that's cool, IF she can just KO Holm and get the hell out of the ring and get shit fixed. it's all happening so fast.
as the blood welled up in her face and she started changing colors, she looked woozy. almost fell over a few seconds before that big kick. Came up sideways, side to opponent, completely clueless what was happening. She probably would have thrown in towel at the end of that period... she was barely standing at that point. Blood pooling and that busted jaw taking more blows.
Rousey acted like a punkass. She believed her own hype. She got a big head. But she was tough IF she stayed up for 6-8 minutes with a shattered face, broken jaw, or something huge like that. Her face was broken long before that brutal kick that ended it.
