Suppression of the peripheral chemoreceptors begins when the P o 2 falls below

A. 50 mm Hg

B. 40 mm Hg

C. 30 mm Hg

D. 20 mm Hg

Expert Solution
Summary Introduction

Introduction:

Peripheral chemoreceptors are located at the bifurcation of the external and internal carotid arteries. The peripheral chemoreceptors are also known as carotid and aortic bodies. These are oxygen sensitive cells that respond to the decreased levels of oxygen in the arterial blood. Peripheral chemoreceptors get activated when the oxygen content is reduced to 60 mm Hg (millimeters of mercury).

Explanation of Solution

Justification for the correct answer:

Option (c) is given as “30 mm Hg.” The peripheral chemoreceptors get activated as the oxygen content falls below 60 mm Hg. The ventilation increases due to the decrease in the oxygen content. The suppression of the peripheral chemoreceptors takes place when the oxygen content falls below 30 mm Hg. Hence, option (c) is the correct answer.

Justification for the incorrect answers:

Option (a) is given as “50 mm Hg...
