Quizplus · Accepted Answer

Breathing is primarily regulated by chemical sensors in the body that measure the concentration of oxygen, carbon dioxide, and pH levels in the blood. These sensors are located in the arteries and communicate with the respiratory center in the brainstem to adjust the rate and depth of breathing. Erythropoietin, red blood cell concentration, and hemoglobin levels may indirectly affect breathing by influencing the oxygen-carrying capacity of the blood, but they are not the primary regulators of breathing. The lungs and larynx are structures involved in breathing, but they do not regulate breathing.
