Chemoreceptors in the cardiovascular system
WebThe book will contain reviews and brief research articles from the participants attending the International Society for Arterial Chemoreception (ISAC) meeting, to be held in Lisbon in Portugal in June/July 2024. Since ISAC was first established, almost 70 years ago, many advances in the classical field of arterial O2, CO2 and pH sensing have been achieved … WebWhen the medulla oblongata receives signals from baroreceptors and chemoreceptors, it changes the rate at which the sino-atrial node (SAN) fires (learn more about the SAN here). If blood pressure or oxygen concentration is low, the cardiovascular control centre increases the rate of SAN firing through activation of the sympathetic nervous system.
