What is the medical term meaning voluntary increase in the rate and depth of breathing? What factors are most important in triggering the changes in breathing rate? Chemicals - most important are the concentrations of CO2, hydrogen  ions and O2 in the blood. Chemoreceptors are located in the  respiratory center, the carotid bodies and tâ¦he aortic bodies which  detect the levels.
Chemoreceptors that regulate the depth and rhythm of breathing are broken down into two categories. 1  central chemoreceptors are located on the ventrolateral surface of medulla oblongata and detect changes in pH of cerebrospinal fluid. 2  peripheral chemoreceptors: consists of aortic and carotid bodies. Examples of distance chemoreceptors are: 2  olfactory receptor neurons in the olfactory system: Olfaction involves the ability to detect chemicals in the gaseous state. 3  In vertebrates, the olfactory system detects odorants and pheromones in the nasal cavity.
