Chemosensitive area of respiratory centre in medulla is affected byA. less `CO_(2)` and `H^(+)` ionsB. less `O_(2)` and `H^(+)` ionsC. excess `CO_(2)` and `H^(+)` ionsD. excess `O_(2)` and `H^(+)` ions |

Answer» Correct Answer - C Respiratory rhythm centre is a specialised centre present in the medulla of the brain which is primarily responsible for the regulation of respiration. A chemosensitive area situated adjacent to the rhythm centre is highly sensitive to changes in `CO_(2)` and hydrogen ion concentrations in blood. Increase in `CO_(2)` and `H^(+)` ions stimulate this centre, which in turn stimulate the rhythm centre to make necessary adjustments in the respiratory process by which these substance can be eliminated. |
