Describe the bainbridge reflex
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. This results in an increase in the pressure of the right atrium, which stimulates the See more • Low pressure receptor zones • High pressure receptor zones See more WebOther articles where pressure receptor is discussed: Bainbridge reflex: Special pressure sensors called baroreceptors (or venoatrial stretch receptors) located in the right atrium of the heart detect increases in the volume and pressure of blood returned to the heart. These receptors transmit information along the vagus nerve (10th cranial nerve) to the central …

WebQuestion: Describe All possible outcomes for the baroreceptor reflex and the Bainbridge reflex in terms of locations where the reflexes are detected, the cardiac centers and their appropriate responses, and how the heart rate and blood pressure are affected (not just those segments that were stimulated during tab). WebYour baroreceptor reflex is a series of quick actions your body takes to keep your blood pressure in a normal range in response to an abrupt change in position (particularly, a seated/lying down position to a standing position). It’s the most important way your body regulates blood pressure during these short-term events.

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 …
