[X-Men] What are the hoses on Apocalypse's arms for?

Do they enhance circulation? Do they feed him some potent liquid? Are they purely cosmetic?

He's armored by the Four Hosemen of Apocalypse.  

But yes, as Common-Additional says, he has Celestial tech *in addition to* being an Alpha/Omega level mutant and being the product of alien genetic tinkering.  

So, while the pipes foreshadow his eventual affiliation with/against Cable, the armor more generally implies the foes of Apocalypse... are hosed.
