Control of Breathing. The primary respiratory muscle is the diaphragm, which is innervated by the phrenic nerve. In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.. The respiratory centers that control your rate of breathing are in the brainstem or medulla. The brain is the primary controller of respiratory rate. How Is Your Breathing Rate Controlled? respiratory control centers: The medulla which sends signals to the muscles involved in breathing, and the pons which controls the rate of breathing. Many factors affect the rate of cellular respiration in living things. In what ways are the respiratory system and the circulatory system related? The nerve cells that live within these centers automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals. If one had to invent an answer to the question, one might sensibly intuit that increased work by muscles leads to an increased rate of metabolism which then increases the production of COIn short, they removed most of their brains and then stimulated their diencephalon locomotor regions to make these cat-zombies walk on treadmills. 3 4 5.
