Question

Human beings a significant ability to maintain and moderate the respiratory rhythm to suit demands of the body. For it we have –

Respiratory rhythm centre in medulla = R

Pneumotaxic centre in Pons = PT Chemosensitive area in medulla = C₁

Peripheral chemoreceptors in aortic arch and carotid artery = C₂ Find out the correct path for regulation of respiration

• A. C₂→R→PT→C₁
• B. $P T \rightarrow \underset { \substack { \uparrow \\ C _ { 1 } } } { R } \leftarrow C _ { 2 }$
• C. $C _ { 1 } \rightarrow \underset { \substack { \uparrow } } { P T } \rightarrow C _ { 2 }$
• D.

Answer 1

Answer: (B)

$P T \rightarrow \underset { \substack { \uparrow \\ C _ { 1 } } } { R } \leftarrow C _ { 2 }$
