Clusters of cells located near the carotid artery in the neck sense the amount of oxygen in the blood. if the level is too low, these arteries send signals to the brain that result in an increased breathing rate, which brings more oxygen into the body. this is an example of which of the following? negative feedback to amplify small signals negative feedback to maintain homeostasis positive feedback to maintain homeostasis positive feedback to amplify small signals
