Q: Which gas is primarily monitored by the body to regulate breathing rate?

Solution: The body primarily monitors carbon dioxide levels to regulate breathing rate, as high levels indicate the need for increased respiration.

Steps: 5

Step 1: Understand that the body needs to breathe to get oxygen and remove carbon dioxide.
Step 2: Know that carbon dioxide (CO2) is a waste product produced when the body uses oxygen.
Step 3: Realize that when CO2 levels in the blood rise, it signals the body that it needs to breathe more to get rid of the excess CO2.
Step 4: Recognize that the brain monitors CO2 levels closely to adjust the breathing rate accordingly.
Step 5: Conclude that the primary gas monitored by the body to regulate breathing is carbon dioxide.
