Full Transcript: A fan named Phillip called in asking how the body regulates blood pressure during exercise. The answer lies in the baroreceptor reflex. Baroreceptors in the carotid artery and aortic arch detect increased blood pressure during running. This triggers a response in the cardiac and vasomotor control centers, which decrease heart rate and cause blood vessels to dilate. These control centers maintain blood pressure and heart rate within normal ranges even during exercise. Before you keep going, Colin, looks like we're getting a phone call from a fan. Let's see what question they have. Hey, guys! This is Phillip. I often experience high blood pressure, and my doctor recommended I go on daily runs. How does the body even know how to regulate blood pressure? Hi, Phillip. Let me see if I can help you with that. I believe your question relates to the baroreceptor reflex. Baroreceptors in the carotid artery and aortic arch detect an increase in blood pressure from the heart rate increased during running. This causes an increase in the frequency of action potential sent down the glossopharyngeal and vagus nerve to the cardiac and vasomotor control centers. In response, the cardiac control centers increase the parasympathetic stimulation to the SA node, which decreases the heart rate and also decreases the sympathetic stimulation, which also decreases the heart rate. The vasomotor control center decreases sympathetic stimulation to blood vessels, causing vasodilation. These control centers allow blood pressure and heart rate to stay within homeostatic ranges when blood pressure gets too high or low at all times, including when we are running. I hope that helped you out, Phillip. I'm going to pass the mic back to Colin.
