A definition essay, however, needs to be several. paragraphs. Therefore, the definition must be extended to include examples, details, personal. experience, description, causes, effects, analysis, etc.
Best Answer: An increase in blood CO2 increases respiration. A decrease in blood O2 increases respiration. An increase in blood pH (meaning it becomes less acidic, more alkali) decreases respiration.A decrease in blood pH (meaning it becomes more acidic) increases respiration.The body has both peripheral (in the body) and central (in the brain) chemoreceptors that monitor levels of O2, CO2, and pH.nswers.

1 The increased rate of breathing returns the carbon dioxide concentration to normal and the breathing rate then slows down.  Hydrogen ion (pH): The peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF. If the hydrogen ion concentration increases (that is, if the fluid becomes more acidic), then the chemoreceptors tell the respiratory centers to speed up.
