Heart rate is affected by blood pressure (detected by baroreceptors in the aorta/carotid arteries) and by changes in blood chemicals like CO2 concentration (detected by chemoreceptors in the aorta/carotid arteries and medulla).
La frecuencia cardíaca se ve afectada por la presión sanguínea (detectada por barorreceptores_ en la aorta y arterias carótidas) y por cambios químicos en la sangre, como la concentración de CO2 (detectada por quimiorreceptores en la aorta, arterias carótidas y médula).
