Breathing is produced in brainstem respiratory centers and is modified by afferent input and central processes. Within the heart there is a region that functions as the pace-maker: keeps our heart beating continuously and rhythmically. Within the brain stem there is a region called the pre-botzinger complex which functions in the same manner for breathing: it is much more complex to the heart pace-maker in the sense that there aren"t simply. There"s a network of neurons that functions together in order to generate a single breath. If one region is failed, there are other regions that can take up the task. In the various regions of the brain a basic rhythm is produced integrated and amalgamated with feedback from a variety of central and peripheral control systems which come together and regulate breathing.
