What are four locations for sensors to control breathing rate?

Four locations for sensors to control breathing rate include the carotid bodies, which are sensitive to changes in blood oxygen levels; the aortic bodies, which detect blood gas concentrations; the medulla oblongata, which regulates the automatic control of breathing; and the stretch receptors in the lungs, which respond to lung inflation and help modulate the breathing rate. These sensors work together to maintain homeostasis by adjusting respiration according to the body's needs.
