History US Government. The Ninth Amendment was part of the Bill of Rights that was added to the Constitution on December 15, 1791. It says that all the rights not listed in the Constitution belong to the people, not the government. Judge Robert Bork called the Ninth Amendment a meaningless inkblot on the Constitution. 2  The Ninth Amendment was cited by the Supreme Court in the famous Roe v. Wade case. 3  Some judges have said that this amendment is not a source of additional rights, but simply a rule about how to read the Constitution.
Additional Readings. Systemic arterial blood pressure usually is measured using an instrument called a sphygmomanometer. This device consists of an inflatable rubber cuff connected by tubing to a compressible bulb and a glass tube containing a column of mercury.
In the same way, your blood vessels are pipes. They take the output from the pump and distribute it throughout the body. A blood pressure gauge is simply a way to measure the performance of the pump and the pipes. There are two numbers in a blood pressure reading: systolic and diastolic. For example, a typical reading might be 120/80. When the doctor puts the cuff around your arm and pumps it up, what he/she is doing is cutting off the blood flow with the pressure exerted by the cuff.
