Match the respiratory system component with its function:

<p>Respiratory Rhythm Center (Medulla) = Primary regulation of respiratory rhythm. Pneumotaxic Center (Pons) = Moderates the function of the respiratory rhythm Center. Chemosensitive Area = Detects $CO_2$ and $H^+$ concentrations. Aortic Arch and Carotid Artery Receptors = Recognize changes in $CO_2$ and $H^+$ concentration and send signals to the rhythm center.</p> Signup and view all the answers

Respiratory Rhythm Center

Brain region primarily responsible for regulating breathing rhythm.

Pneumotaxic Center

Brain center in the pons that moderates the respiratory rhythm center.

Chemosensitive Area

Area near the rhythm center, sensitive to CO2 and hydrogen ions.

Aortic and Carotid Receptors

Detect changes in CO2 and H+ levels, signaling the rhythm center.
