where are the chemoreceptors for cvs regulation present ? are they same as respiratory chemoreceptors ? please someone explain as regulation part of cvs is my weak area
Chemoreceptors are the carotid bodies and aortic bodies… They are perfused by blood (CVS) and they too require Oxygen (Respiration)… When any of these two levels falls they will be activated
Baroreceptors for CVS regulation are present in carotid sinus and aortic arch !
There are several chemicals that regulate bp like urotensin, endothelin which are vasoconstrictors
Histamine ,cgrp , anp are vasodilators which decrease bp
Central chemoreceptors for respiration are present in ventral surface of medulla
Peripheral in aortic and carotid bodies !
