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.
The baroreceptor reflex acts to decrease heart rate when BP rises. When blood volume is increased, the Bainbridge reflex is dominant; when blood volume is decreased, the baroreceptor reflex is dominant. The Bainbridge reflex is seen in dogs, but experiment has shown that it is not as significant in primates.
