No it's not. Most horns started out like the old long horns you see in Cartoons. They used the length of the horn to get a particular pitch. they eventually curled up like the french horn. They added valves in I am not a brass major. You should probably ask a musicologist that is a little more knowledgable than I.
The four orchestral familes are percussion, brass, strings and woodwinds. However, this is not the true order because persussion instruments do not always have a defined pitch, and they could be in any pitch range. The other three families, brass, string and woodwinds, can be placed in pitch order:Woodwinds (main and related)BrassStrings

Oh, isn't that just wonderful? When you play a brass instrument, it's like creating a beautiful little dance with your lips and the mouthpiece. Just imagine your lips gently buzzing together, like little bees making music. Keep exploring and practicing, and you'll soon be painting lovely melodies with your instrument.
This is true.
Brass instruments are different from all the other instruments in that the person playing is solely responsible for the sound of the instrument. Brass instruments require the player to buzz their lips in the mouthpiece. This sound reverberates throughout the instrument and produces the sound that comes out of it. This differs from other instruments, where the player makes part of the instrument vibrate (i.e. reed, string, drum head). The pitch of brass instruments is then changed by changing the frequency of the vibrations created by the lips. If you buzz your lips at a higher pitch, the instrument plays a higher note. The opposite is also true. Buzzing your lips at a lower pitch creates a lower note.

That is so true! In fact it is the function of the heart valves.
String instruments, symbols and electric guitar
true. Heart sounds or lubb dubb are created when the valves of the heart snap shut
True
The AV valves are closed
In dungeons and dragons 3.5, the weakest of the true dragons was the white dragon. Between the copper and the brass, an adult copper dragon has a challenge rating of 14 as opposed to the 12 of the brass, so the brass is weaker.
