[General Fantasy] Does centaurs have two sets of each organ?

Two hearts, two stomachs, two sets of lungs, etc.

Depends on which breed or location, or whether they're created or natural but normally no.

Most centaur aren't *literally* a human and a horse mashed together. You wouldn't have a human heart and a horse heart. You *might* have multiple organs, but in the same way that cows etc have multiple stomachs. They're just naturally evolved duplicates for alternate functions, not copies. You might have a primary heart and a smaller, secondary heart for making sure blood gets circulated through the upper extremities. 

Of course, if your centaurs are the results of magical or alchemical grafting, then all bets are off.
