WebMay 3, 2024 · When a partial pressure of oxygen (pO2) is detected by the chemoreceptors, they will communicate with the brain to trigger a biological response such as an increase in respiratory rate, redistribution of blood flow to hypoxia-sensitive organs like the kidneys, and an increase in cardiac output. WebConversely, a drop in blood pressure decreases the frequency of action potentials generated by the receptors. 2. ... One way to maintain oxygen delivery even if the blood …
