Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.

<em>Human DNA Polymerase</em><em> </em><em>cannot be used in PCR</em><em> </em><em>beca</em><em>use</em><em> </em><em>it </em><em>i</em><em>s</em><em> adapted for a range that covers our body temperatures - a narrow range around 37°C.
