Question
Fill up the blanks in the following paragraph by selecting the correct option.
Human beings have a significant ability to maintain and moderate the respiratory rhythm, to suit the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called ___(i)___ is primarily responsible for this regulation. Another centre present in the pons region of the brain called ___(ii)___ can moderate the functions of the respiratory rhythm centre. Neural signal from this centre can reduce the duration of ___(iii)___ and thereby alter the respiratory rate. A __(iv)__ is situated adjacent to the rhythm centre which is highly sensitive to CO2 and hydrogen ions.

Solution
The correct option is B (i)Respiratory rhythm centre (ii)Pneumotaxic centre (iii)Inspiration (iv)Chemosensitive area
Human beings have a significant ability to maintain and moderate the respiratory rhythm, to suit the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called (i) Respiratory rhythm centre is primarily responsible for this regulation. Another centre present in the pons region of the brain called the (ii) Pneumotaxic centre can moderate the functions of the respiratory rhythm centre. A neural signal from this centre can reduce the duration of (iii) inspiration and thereby alter the respiratory rate. A chemosensitive (iv) area is situated adjacent to the rhythm centre which is highly sensitive to CO2 and hydrogen ions.So, the correct answer is '(i)Respiratory rhythm centre (ii)Pneumotaxic centre (iii)Inspiration (iv)Chemosensitive area'.
