[DC] Do the Flash's insides move at super speed?

E.g, does his heart beat a billion times a second? Does his blood rush through his veins faster than light? Do the electrons in his brain buzz around the same speed he runs?

He *can* speed his insides up, as evidenced in Justice League and the CW Flash show when his heartbeat went so fast he appeared to flatline. In addition, one of his many secondary abilities is super-metabolism. So his body can speed up internally. But just as he can slow down his brain and jaw fast enough to talk into a radio while moving at super-speed, I'd say it's a fair bet he can adjust the speed of his insides while running to suit his needs.
