Answer 2

Answer:

The correct option is (C).

Explanation:

• Hypercapnia or hypercarbia is the medical term for CO2 retention. An arterial or venous blood gas can be used to diagnose hypercapnia, which is frequently brought on by hypoventilation or a failure to remove too much CO2.
• Respiratory acidosis can result from increased CO2 levels in the blood. The chemoreceptor reflex is principally responsible for maintaining normal respiratory drive and, consequently, CO2 exhalation.
• The ability of the body to react to variations in pO2, pCO2, and pH depends on the chemoreceptor reflex.
• There are two types of chemoreceptors: peripheral and central.
• The carotid and aortic bodies are home to peripheral chemoreceptors. The primary sensor of elevated pCO2, decreased pO2, and generally lowered pH is the carotid body.
