Answer:
1. High Co2
2. signal sent to respiratory control center
3. The diaphragm acts to increases breathing
4. The lungs bring in O2 and release CO2.
5. The decrease in CO2 reestablishes homeostasis
Step-by-step explanation:
The respiratory system is an example negative feedback
High Co2 --> a signal is sent to the respiratory control center to increase breathing. --> The diaphragm acts to increases breathing. The lungs bring in O2 and release CO2. The decrease in CO2 reestablishes homeostasis
