Blood pressure is defined as the blood pressure of the arteries and veins that pass through the body during the feeding of various parts of the body during the so-called circulatory system, where the blood circulation begins to contract the heart muscle and blood flows from all over the body through the aorta, which is the largest arteries in the body, The muscle of the heart to return blood from the various organs to the heart through the aorta again, and characterized the aorta as well as being the largest arteries at all flexibility, as it expands and contract according to the amount of blood passing through, during the contraction of the heart muscle to push blood to the This is called pressure as systolic pressure and during myocardial infarction. The blood returns to the artery to contract the artery on its content of blood and forces it to return to the heart. This pressure is called diastolic pressure.
Normal blood pressure
Blood pressure is measured by a specialized device at home or by a manual device in the doctor’s office called the mercury pressure gauge. Its reading is in the form of a fracture, for example 120/80, where the number in the numerator represents the value of the systolic pressure and the number which represents the pressure value And the systolic value is always higher than the diastolic pressure value.
Pressure is measured in millimeters of mercury in the case of relaxation and rest. The normal value of the systolic pressure of the adult is between 90 and 140 mm Hg and between 60 and 90 mm Hg, ie, mean 120 and 80.
Periodic examination of pressure
Many people become infected with blood pressure and delay in discovering that the symptoms are usually not clear and distinct, but similar to the symptoms of some other diseases such as influenza, exhaustion and physical and psychological stress, so it is very important to follow blood pressure constantly to avoid any side effects resulting from the rise or decrease from Normal level, high pressure indicates that the heart is having trouble pumping blood, which leads to increased effort, and this may cause many serious diseases in the long term, such as strokes and kidney failure and may lead to death. And the decrease in natural values indicates that the amount of blood rushing from it is not enough to feed the body’s various organs, so the amount of food and oxygen that reaches the members with the blood become less, and this may lead to failure and failure in the function and has a serious risk to the brain, and may lead to Continuous fatigue.
