Question

Quizplus · Accepted Answer

The carotid and aortic bodies are located in the arteries near the heart and neck, respectively, and are responsible for detecting changes in blood PO₂ levels. When there is a large drop in blood PO₂, these receptors stimulate the respiratory centre of the brain to increase breathing rate and depth to improve oxygen uptake by the body.
