Chemoreceptors in the cardiovascular system
WebThese chemoreceptors provide feedback to the cardiovascular centers about the need for increased or decreased blood flow, based on the relative levels of these substances. The limbic system can also significantly impact HR related to emotional state. WebChemoreceptor function. Introduction. The major oxygen sensors in the human body are peripheral chemoreceptors, also known as interoreceptors-as connected with internal organs, located in the aortic arch and in the body of the common carotid artery.
