Describe the bainbridge reflex
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 ... 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.

The pericardium protects the heart against infection and inflammation from the lungs and pleural space. d. It contains pain and mechanoreceptors that can elicit reflex changes in blood pressure and heart rate.
WebThe withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus.
