What Is Blood Pressure?
Most people would like to know: what is blood pressure. Not that, there is no ample definitions existing on the net. Blood pressure measures the pressure on the walls of the artery due to blood. It may be noted that the question of what is blood pressure is applied only with the heart and the functioning of the heart. In the course of its work, the heart pushes the blood through the arteries and this in turn results in the pressure on the walls. When the push is applied to the blood a pressure is noted and when there is no push or when the heart is relaxing there is another value of pressure on the blood. The stronger one is called the systolic and weaker one is called the diastolic blood pressure.
So what is blood pressure? The blood pressure is expressed normally as 120/70 mm of mercury. Here the 120 mm represents the systolic blood pressure and the 70 mm represents the diastolic blood pressure. The blood pressure pushes the blood through the body over the arteries. The blood in turn reaches every part of the body. It is not a question of what is blood pressure anymore. The pressure variation affects the vital organs like brain, kidneys and lungs. Of course, the heart is the first to get affected by the blood pressure increase.
When a person is under stress or under pressure mentally, there is an increase in pressure suitably. This is primarily to increase the blood circulation to the brain thereby making it to work faster and better. So what is blood pressure that causes blood circulation to be also controlled by the physical exercise of the body? When there is more energy needed, the body also goes through the increase in blood flow to help generate more energy that is needed. But the increase in blood flow does not increase the pressure since as per the Bernoulli's law, when there is an increased speed there is a fall in pressure. In line with that, for athletes you will normally find a reduction in pressure below the standard or normal blood pressure.
What is blood pressure is answered if the question why an obese person faces an increased pressure. Apart from this, there is also an increased blood pressure noticed when there is a cardiovascular disease. When such increases in blood pressure occurs, there is an increased incidence of damages to the vital organs. Blood flow is critical to all the organs in the human body. The quantity of blood flow is also crucial. When this flow is disrupted and there is a reduced quantity of blood flowing through the organ, the chances of the organ failing is very high. That is why, what is blood pressure indicates failure of the organs like kidneys. It is important, what is blood pressure is normally answered in the context of how it is caused rather than how to get rid of it.
