The Bainbridge reflex or Bainbridge effect, also called the atrial reflex, is an increase in heart rate due to an increase in central venous pressure. Increased blood volume is detected by stretch receptors (Cardiac Receptors) located in both sides of atria at the venoatrial junctions. See more Francis Arthur Bainbridge described this as a reflex in 1918 when he was experimenting on dogs. Bainbridge found that infusing blood or saline into the animal increased heart rate. This phenomenon occurred even if … See more The Bainbridge reflex and the baroreceptor reflex control heart rate. The baroreceptor reflex can correct for a change in arterial pressure by increasing or decreasing heart rate. In contrast, … See more Bainbridge Reflex is involved in Respiratory Sinus Arrhythmia. During inhalation intrathoracic pressure decreases. It triggers increased venous return which is … See more Increased blood volume results in increased venous return to the heart, which leads to increased firing of B-fibers. B-fibers send signals to the brain (the afferent pathway of the neural portion of the Bainbridge reflex), which then modulates both … See more As venous return increases, the pressure in the superior and inferior vena cava increase.

WebThe Bainbridge reflex occurs when the heart rate increases in response to a rise in atrial pressure and this is a compensatory mechanism since increased right atrial pressures frequently result from elevated left heart pressures from decreased cardiac output. The Bainbridge reflex controls heart rate in response to blood volume and blood volume ... WebJan 1, 2024 · The Babinski reflex tests the integrity of the corticospinal tract (CST).

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 … Webb. It is made up of connective tissue and a surface layer of squamous cells. c. The pericardium protects the heart against infection and inflammation from the lungs and pleural space. d.
