Notes / Explanation
The normal human blood pressure is generally considered to be around one hundred and twenty over eighty, a measurement that is one of the most important indicators of a person's health. Blood pressure refers to the force exerted by the blood against the walls of the blood vessels as it is pumped around the body by the heart. As the heart beats, it pushes blood through the arteries, and this creates a pressure that can be measured. The measurement of blood pressure is expressed by two numbers. The higher number represents the pressure at the moment when the heart contracts and pushes the blood out into the arteries, and the lower number represents the pressure when the heart relaxes between beats and fills again with blood. Together these two numbers give a picture of how hard the heart and the blood vessels are working. A reading of about one hundred and twenty over eighty is taken as a typical healthy value for an adult, although the exact figure considered normal may vary somewhat from person to person and according to age and other factors. Maintaining blood pressure within a healthy range is very important, because both high blood pressure and low blood pressure can be harmful. High blood pressure, in which the force of the blood against the vessel walls is consistently too great, is a common and serious condition that can place strain on the heart and the blood vessels and can, over a long period, increase the risk of serious problems affecting the heart, the brain and other organs. It is sometimes called a silent condition because it often produces no obvious symptoms while still causing damage, which is why regular checking of blood pressure is important. Low blood pressure, on the other hand, can cause symptoms such as dizziness and weakness. Blood pressure is affected by many factors, including diet, physical activity, body weight, stress and general health, and it can often be kept within a healthy range through a sensible lifestyle, while medical treatment is available when needed. For PPSC and other competitive examinations, the key points to remember are that the normal human blood pressure is around one hundred and twenty over eighty, that the higher number represents the pressure when the heart contracts and the lower number the pressure when it relaxes, that blood pressure measures the force of the blood against the vessel walls, and that keeping it within a healthy range is important for good health.
