Blu-ray, also known as Blu-ray Disc (BD) is the name of a new optical disc format that is rapidly replacing DVD. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.
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.
Build-up of CO2 therefore causes an equivalent build-up of the disassociated hydrogen ions, which, by definition, decreases the pH of the blood. The pH sensors on the brain stem immediately sense to this fall in pH, causing the respiratory center to increase the rate and depth of breathing. The consequence is that the P C O 2 {\displaystyle P_{{\mathrm {CO} }_{2}}} (partial pressure of carbon dioxide) does not change from rest going into exercise.
