I think gems' human constructs have everything we have but with missing parts: there's a digestibe system (as said by Pearl), a respiratory system (I don't know how many times I've seen the gems coughing or breathing, complete with the chest expanding), bones, joints (explied I heard the cracking sound from Garnet), a heart (I think), and a brain (they are able to sleep and think like us).
