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.
1 Oxygen: Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers. 2  If the oxygen concentration in the blood decreases, they tell the respiratory centers to increase the rate and depth of breathing. This mechanism prevents damage to the lungs that would be caused by over-inflation. 2  Signals from higher brain centers: Nerve cells in the hypothalamus and cortex also influence the activity of the respiratory centers. 3  During pain or strong emotions, the hypothalamus will tell the respiratory centers to speed up.
