The peripheral chemoreceptors are located in the aorta and carotid arteries, and they deliver blood to the brain.

外周化学感受器位于主动脉和颈动脉，它们向大脑输送血液。

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。
