The central chemoreceptors are located in the medulla oblongata, and they're sensitive to changes in carbon dioxide levels.

中枢化学感受器位于延髓，对二氧化碳含量的变化敏感。

Central chemoreceptors located in the brain sense changes in carbon dioxide, while peripheral chemoreceptors located in the arteries delivering blood to the brain sense changes in both carbon dioxide and oxygen.

位于大脑中的中央化学感受器感知二氧化碳的变化，而位于动脉中的周围化学感受器感知二氧化碳和氧气的变化，这些动脉将血液输送至大脑。
