What is the physiological response to a rise in pressure within the carotid sinus?

Show Answers

Increased depth and rate of breathingElevated levels of carbon dioxide through reflex mechanismsAccelerated heart rate due to reflex actionEnhanced carbon dioxide retention reflex

Explanation

An increase in carotid sinus pressure triggers a reflex that leads to elevated carbon dioxide levels in the blood, known as reflex hypercapnia. This differs from reflex hyperpnea, which involves increased breathing rate and depth, and reflex tachycardia, which is an increase in heart rate.
