Homework Answers
Pulmonary stretch receptors (PSRs) are usually situated among the smooth muscles of the small air ways.
They are usually stimulated due to alteration of shape like stretching of these airways. They are activated during inspiration (Option A).
When Pulmonary stretch receptors via the vagus nerve result in the inhibition of inspiratory stimulus in the medulla and thus inhibits inspiration (Option C) and initiate expiration.
Add Answer to:
12. Pulmonary stretch receptors are activated during: A) inspiration B) expiration C) high 02 levels D)...
