Which receptors detect changes in carbon dioxide and oxygen levels in the blood?

Question

Quizplus · Accepted Answer

Chemoreceptors are specialized receptors that detect chemical changes in the blood and send signals to the brain to regulate breathing. There are separate chemoreceptors for carbon dioxide (CO2) and oxygen (O2) levels in the blood. When CO2 levels rise, the chemoreceptors send signals to increase breathing rate to get rid of the excess CO2. When O2 levels drop, the chemoreceptors send signals to increase breathing rate to bring in more oxygen. Proprioceptors detect changes in body position and movement, baroreceptors detect changes in blood pressure, and mechanoreceptors detect mechanical changes such as touch or pressure.
