Answer 1

• The force which is exerted by the circulating blood on the wall of arteries is called blood pressure.
• There are two types of blood pressure that are systolic blood pressure and diastolic blood pressure.
• Blood pressure is measured by an instrument, which is a sphygmomanometer.
• A sphygmomanometer consists of an inflatable rubber cuff that is wrapped around the upper arm tightly and is connected to an apparatus that measures pressure in terms of the height of a column of mercury.
