Respiratory control centers are located in the_ A) midbrain and medulla B) medulla and pons C) pons and midbrairn D) upper spinal cord and medulla 40. Which center is located in the pons? A) pontine respirator group (PRG) B) expiratory center C) inspiratory center D) pacemaker neuron center 41. The conducting passageways of the respiratory system include all the following EXCEPT a) nose b) pharynx c) larynx d) trachea e) alveoli BONUS: The respiratory conducting passageways perform all the following functions EXCEPT a) allow air to reach the lungs b) purify air c) humidify air d) exchange gases e) warm incoming airExplanation / Answer
answer38) the naswer for the above question is A which is Pulmonary ventilation and it is commonly known as breathing it includes inhalation and exhalation. this process occurs due to the presence of air pressure.
answer39) the naswer for the above question is B because the centre is located in the brain stem which consist of medulla and pons. in medulla dorsal and ventral respiartory group is persent and in pons PONtine respiratory group is present.
answer40) in PONS pontine respiartory group is present which includes pneumotoxic and apneustic centres.
answer41) answer will be alveoli which comes under the respiratory zone which helps in exchange of oxygen.
bonus answer will be d which is exchange the gases. rest all is the function of conducting passageways.
