Interpreting cardiac echo for aorta

Hi there could you possibly give me the standard "average" measurments for an adult regarding the different aortic measurments specifically the AV annulus, the aortic sinus, sino tulular junction and ascending aorta?  Again these would be adult measurments I am female not sure if that makes much difference.

Thank you.  I have searched high and low and cannot find a site that offers what they consider normal in these areas.

There can  be some variablility based on body size but 3.7 cm would be a good average.

Thank you so much.  My aorta states 2.5 then there are other measurments like the annulus(not sure if this is the root0?  The sinus and sinotubular junction and ascending

Perhaps you could help me understand what those above things are? They all appear to have individual measurments.

Thanks again for taking your time to respond to me, I sincerely appreciate it.
