Chemoreceptor reflex flow diagram
WebThe chemoreceptor reflex works to ensure sufficient delivery of oxygen when blood gas levels change. Located near the baroreceptors in structures called the carotid and aortic … WebA reflex arc is a pathway along which impulses are transmitted from a receptor to an effector without involving ‘conscious’ regions of the brain. As it does not involve the brain, a reflex response is quicker than any other type of nervous response. Examples of simple reflex actions that are coordinated by these pathways are: Removing the ...
