Some diseases have become so widespread in recent times that you are not even surprised when you know that one of your friends or relatives has been infected by one of them. The incidence of these diseases can be hereditary or due to some factors. The best known of these is abnormal blood pressure. Abnormal blood pressure is divided into two parts, high blood pressure and low blood pressure. High and low blood pressure share similarities in some aspects and differ in others. Blood pressure is the force with which the heart pushes blood against the sides of the arteries. Basically, the function of blood pressure is to assist the blood in its tasks. For example, blood pressure not only diffuses white blood cells, which are part of the immune system, but also delivers oxygen, nutrients, and hormones throughout our bodies (1). As long as the blood pressure is at its normal level, it can perform its tasks perfectly. The purpose of normal measurement is not a certain number, but it is a specific range because blood pressure changes to meet our body's needs (2). For example, blood pressure when you exercise is different from when you sleep. Also, there is a way to know your blood pressure. The tool we use to measure our blood pressure is the sphygmo. The device contains two numbers, the upper one and the lower one. If it is higher than 12080, you have hypertension, the medical name for high blood pressure, and if it is lower than 9060, you have hypotension, the medical name for low blood pressure (3). In conclusion, it is obvious that blood pressure plays a vital role in our body and we should help it continue its function by trying to maintain blood pressure at its normal level. Despite hypertension...... paper medium......great risk to our health. In my opinion, visiting your doctor regularly could save you from getting sucked into this vortex. Works Cited1. M. Markus.
