My khajiit tank has 36k health with the Lord while you have 44k. Is the difference purely cause you're Imperial?
And here is Khajiit:
Health 41258...
Magicka 18868...
Stamina 18505...

As you see, it's still 5k more than 36k Health. So you are either missing gear, enchants or food. Another thing is, you would want to sacrifice some more Health to bring Stamina just a bit higher to make sure you restore Stamina when an Orb is popped. And here is what you would have in that case:
Health 40749...
Magicka 18868...
Stamina 18913...
So yeah. It's pretty much impossible to have 36k unless you are running completely different build.
I just made my Tank, only the Jewelry is gold and I don't have good traits on the Monster Set yet, but I'm wearing Ebon and Dragonguard with Lord Warden. 6/1 heavy and medium. Most health glyphs with two magick glyphs instead of the tri-stat, and a max health and stam blue food. 4% undaunted mettle.
Which puts me at Health: 36.8k Stamina: 21k Magic: 14k
Ok I tried to get those stats using the Build Editor. Here is what I got: http://en.uesp.net/wiki/Special:EsoBuildData?id=78507
This must be it. I simply couldn't get your stats in any other way. Anyway, it is just whole different than what I use. Biggest difference is Attributes are not into Health and gear is different.
Anyway, I think I explained enough. Your build is just different than what I explained here otherwise it's impossible to get those stats. If you want to go with this build, just use this link: http://en.uesp.net/wiki/Special:EsoBuildData?id=74221
