Exam 2 Anatomy

Inhibition of medulla oblongata chemoreceptors and respiratory muscles has what effect on respiratory rate, elimination of CO2 at alveoli, and arterial PCO2? decreased respiratory rate, decreased elimination of CO2 at alveoli, and increased arterial PCO2 increased respiratory rate, increased elimination of CO2 at alveoli, and decreased arterial PCO2 decreased respiratory rate, increased elimination of CO2 at alveoli, and increased arterial PCO2 increased respiratory rate, increased elimination of CO2 at alveoli, and increased arterial PCO2 increased respiratory rate, decreased elimination of CO2 at alveoli, and decreased arterial PCO2

decreased respiratory rate, decreased elimination of CO2 at alveoli, and increased arterial PCO2

Prolonged inspirations can result from stimulating the ________ center. expiratory pneumotaxic apneustic chemoreceptor baroreceptor

apneustic

The apneustic centers of the pons monitor blood gas levels. inhibit the pneumotaxic and inspiratory centers. provide stimulation to the inspiratory center. alter chemoreceptor sensitivity. generate the gasp reflex.

provide stimulation to the inspiratory center.

The pneumotaxic center of the pons prolongs inspiration. stimulates the dorsal respiratory group. modifies the rate and depth of breathing. sets the at-rest respiratory pattern. suppresses the expiratory center in the medulla.

modifies the rate and depth of breathing
