Describe what happens in the respiratory system when you run to catch a bus by placing the following in order (#1-7). Consider that the running will have caused an increase in cellular respiration, which results in an increase in CO2 (this is the change in the variable). The increase in CO2 will be detected by the brain, which will ultimately cause an increase in ventilation. Blood CO2 levels increased and O2 levels decreased. Increased ventilation results. Chemoreceptors detect decreased O2 and increased concentration of CO2/decreased pH. Return to normal CO2 and O2 levels. Respiratory centers increases its stimulation of spinal nerves (phrenic and intercostal). Increased frequency and degree of contraction of respiratory muscles. Central and peripheral chemoreceptors stimulate the respiratory centers in the brainstem. Increased cellular respiration in response to the running.
