baroreceptor reflex मीनिंग इन हिंदी

उदाहरण वाक्य

1. The Bainbridge reflex and the baroreceptor reflex control heart rate.
2. Some research suggests the existence of intracranial baroreceptors to trigger specific Cushing baroreceptor reflex.
3. The cardiac centers monitor baroreceptor firing to maintain cardiac homeostasis, a mechanism called the baroreceptor reflex.
4. The baroreceptor reflex can correct for a change in arterial pressure by increasing or decreasing heart rate.
5. Generally, the baroreceptor reflex is not targeted in hypertension because if blocked, individuals may suffer from orthostatic hypotension and fainting.
6. The main limiting side-effects of alpha antagonists is that the baroreceptor reflex is disrupted and thus this can cause postural hypotension.
7. However, because dihydropyridine CCBs result in a decrease in blood pressure, the baroreceptor reflex often initiates a reflexive increase in sympathetic activity leading to increased heart rate and contractility.
8. Angiotensin II increases thirst sensation ( dipsogen ) through the subfornical organ of the brain, decreases the response of the baroreceptor reflex, and increases the desire for sympathetic fibers.
9. If blood pressure falls, such as on orthostatic hypotension or in hypovolaemic shock, baroreceptor firing rate decreases and baroreceptor reflexes act to help restore blood pressure by increasing heart rate.
10. Since moment-to-moment blood pressure regulation is carried out by the sympathetic nervous system ( via the baroreceptor reflex ), calcium channel blockers allow blood pressure to be maintained more effectively than do beta blockers.
