Blood is the red liquid that gives life to our bodies. Without it, no human being is alive, which is pumped from the source of the heart to reach all parts of the body through the blood vessels. It moves between all the tissues and even among the smallest cells smoothly and easily, so that it can transport nutrients and oxygen It also discharges it from waste and carbon dioxide and sends it to the output devices until it is discharged outside the body. The blood also performs many important functions within the body such as regulating its temperature, protecting the body against foreign objects because it contains white blood cells E, and many other functions.
The blood pressure is a blood drive to the walls of the blood vessels as it travels through the bloodstream, which starts from the heart with a contraction to push all its content from the blood to the aorta, which in turn works to deliver it to the rest of the vessels The blood in the body, and then spread until the blood is filled and re-contraction again and so on.
Blood pressure should be within certain limits if increased or decreased will show complications that may endanger human life, the average natural blood pressure 75/115 mmHg, and in the case of relaxation, the average blood pressure is 80/120 mmHg, and every human being It is possible to measure blood pressure in two ways: the electronic blood pressure monitor located at home, or the manual at the doctor, also called the device Mercury, which is the most accurate and most secure, or measuring blood pressure without a device Which we will talk about in this article.
