The odds have been set and poll positions assigned for Saturday's Kentucky Derby, often called the "most exciting two minutes in sports."
The big question: Does odds-on favorite Brother Derek (3-1) have a big enough spleen to win?
Or will undefeated and second-ranked Barbaro (4-1) suck in enough oxygen to earn a victory lap? Maybe Flashy Bull, a 50-1 long shot, has already made up his mind to wear the rose blanket awarded in the winner's circle.
These are the questions Kenneth McKeever ponders when considering the science that separates the winners from the also-rans.
Spleen of a champion
McKeever works at the Equine Science Center at Rutgers University. He knows that horses have evolved several physiological features that make them ideal for running. For example, horses can breathe only through their nostrils, which are situated on the sides of their snouts. This is likely an adaptation for preventing kicked-up dust and dirt from entering their lungs when running with their mouth open.
Derby contenders keep one of their best tricks hidden close to their hindquarters.
"Horses have what I call a 'natural blood doper'?a huge spleen that stores a blood supply very rich in red blood cells," McKeever says.
