Google Scholar solves this problem by providing books, articles and even legal documents on virtually any subject. (There is no sound.) (01:53)

Blood pressure is normally tightly controlled in the face of large variations in blood flow required by activities such as vigorous exercise.

The noradrenaline then diffuses to the blood vessel wall, where it interacts with a specific molecular sit
