With your partner read through the following scenario and identify each component of the feedback loop. Is this a positive or a negative feedback loop? Is this facilitated by the nervous system, endocrine system or both? How can you tell?

Carbon Dioxide - When we exercise our muscles give off carbon dioxide as a waste product. This increase in the level of carbon dioxide in the blood. Receptors in the carotid arteries sense the change in carbon dioxide and send a message to the brain. The brain will stimulate the lungs to increase respiration. This will lower the amount of carbon dioxide in the blood.
