WebThe Bainbridge reflex describes how an increase in venous return results in an increase in heart rate (9). This effect is hypothesized to occur via stretching of the sinoatrial node. The immediate increase in contractility of cardiomyocytes upon stretch is described by the Frank–Starling mechanism (10). WebThe term ‘arterial baroreceptor reflex ’ is used to refer to a variety of physiological responses elicited by changes in baroreceptor afferent activity. While the baroreceptor reflex is often used in specific reference to the reflexive change in ABP and heart rate brought about by changing autonomic outflow to the heart and vasculature, there are a … dallas county treasurer iowa phone numberWebThe Bainbridge reflex is elicited as a result of an increased volume of blood in the heart, which causes sympathetic nervous system stimulation. Stretch receptors are located in the right atrium, junction of the vena cava, and pulmonary veins. The Sinoatrial node is involved in this process and can increase heart rate by 10% to 15%. dallas county tx assessor page

"WebCardiovascular reflex responses to visceral afferent stimulation are either excitatory or inhibitory (Fig. 35.3).In this respect, stimulation of vagal afferents causes reflex cardiovascular inhibition, including decreased heart rate, blood pressure, and myocardial contractility, consequent to reduced sympathetic outflow to the heart and blood vessels … " - Describe the bainbridge reflex
