It's a spleen that any elite athlete would envy. When the horse is just standing around, the percentage of oxygen-carrying red blood cells in its circulatory system runs around 35 to 40 percent. Blood in its huge spleen â 3 to 4 feet long, 8 inches wide, and 4 inches thickâis a whopping 80 percent red blood cells. When the horse starts its gallop, the surrounding muscles clamp down on the spleen like a bagpipe and squeeze all that extra blood into the circulation system.
