With powder coating, the bottom line is that the aluminum is covered with a coating which cannot be repaired should any peeling or blistering occur. Polished stainless steel differs from powder coating primarily in that the base material is not covered with a coating and the materials are substantially different.
The baroreceptor reflex or baroreflex is the body's way of responding to a change in blood pressure. Baroreceptors in the arteries notice that something has changed. When they sense a change in pressure, they send out signals through nerves to a part of the brain called the brainstem.
Baroreceptors transmit changes in blood pressure to the brain. Blood pressure is constantly monitored by your body and adjusted constantly to meet the needs of your body. This monitoring is performed by baroreceptors. Baroreceptors are special receptors that detect changes in your blood pressure. Baroreceptors are found within the walls of your blood vessels. The aorta and the carotid sinus contain important baroreceptors which constantly monitor blood pressure fluctuations.
